  3. A Public Presentations of Gendered Bodies: A Look at Gay and Lesbian Online Dating Profiles

    Directory of Open Access Journals (Sweden)

    Andrew Latinsky

    2012-10-01

    Full Text Available This paper examines how stereotypes and media presentations related to gender norms influence public presentations of gay men and lesbian women. Using online profiles from the online dating website Match.com, this paper examines the body types daters use to describe themselves, their ideal date, and if the poster has a photograph of themselves on their profile. These profiles are used as a method of observing public presentations that are in a unique situation to be tailored towards notions of publically displayed social desirability. Findings indicate that gay men present their online bodies as stereotypically masculine and athletic, while lesbian women are willing to display a slightly broader range of body types. In addition, regardless of gender, both gay men and lesbian women present their ideal dates as stereotypically attractive, with gay men having a particular affinity for dating athletic men. Regression analysis suggests that intersectional variables such as race and age influence a person’s willingness to display a profile picture in the public arena. Overall, this study concludes that heteronormative standards of masculinity combined with structural influences from both the media and peer groups likely have an impact on gay men’s ideal gendered body, while the comparative exclusion of lesbian women from these media influences allow other experiences of gender norms slightly more freedom.

  10. Including autapomorphies is important for paleontological tip-dating with clocklike data, but not with non-clock data.

    Science.gov (United States)

    Matzke, Nicholas J; Irmis, Randall B

    2018-01-01

    Tip-dating, where fossils are included as dated terminal taxa in Bayesian dating inference, is an increasingly popular method. Data for these studies often come from morphological character matrices originally developed for non-dated, and usually parsimony, analyses. In parsimony, only shared derived characters (synapomorphies) provide grouping information, so many character matrices have an ascertainment bias: they omit autapomorphies (unique derived character states), which are considered uninformative. There has been no study of the effect of this ascertainment bias in tip-dating, but autapomorphies can be informative in model-based inference. We expected that excluding autapomorphies would shorten the morphological branchlengths of terminal branches, and thus bias downwards the time branchlengths inferred in tip-dating. We tested for this effect using a matrix for Carboniferous-Permian eureptiles where all autapomorphies had been deliberately coded. Surprisingly, date estimates are virtually unchanged when autapomorphies are excluded, although we find large changes in morphological rate estimates and small effects on topological and dating confidence. We hypothesized that the puzzling lack of effect on dating was caused by the non-clock nature of the eureptile data. We confirm this explanation by simulating strict clock and non-clock datasets, showing that autapomorphy exclusion biases dating only for the clocklike case. A theoretical solution to ascertainment bias is computing the ascertainment bias correction (M k parsinf ), but we explore this correction in detail, and show that it is computationally impractical for typical datasets with many character states and taxa. Therefore we recommend that palaeontologists collect autapomorphies whenever possible when assembling character matrices.

  12. Adolescent Perceptions of Dating Violence: A Qualitative Study.

    Science.gov (United States)

    Taylor, Sarah; Calkins, Carrie A; Xia, Yan; Dalla, Rochelle L

    2017-08-01

    Scholars have identified dating violence as a public health issue among adolescents. Yet, minimal research has detailed adolescents' perceptions of dating violence, specifically gender differences in perceptions. Research suggests that in order for dating violence prevention and intervention to be effective, services need to be delivered in a manner that is understood by adolescents. Therefore, this study used a qualitative phenomenology study to investigate adolescents' perceptions of dating violence, including gender differences in adolescents' perceptions. Thirty adolescents between the ages of 14 and 19 from a Midwest public high school participated in focus groups. Focus group participants were asked semistructured interview questions regarding the definition of dating violence, risk and protective factors for dating violence, support for victims and perpetrators, and prevention efforts. Data were analyzed using qualitative content analysis methods, and common themes were identified. Adolescents' language revealed gender differences in perceptions toward dating violence. Males perceive dating violence through action, perpetration, and physical consequences. Females discuss dating violence by relating to the victim and the victim's emotions. Although gender differences existed in participants' perceptions, both males and females explained that dating violence is more often perpetrated by females, despite the view from society that males are more likely to perpetrate dating violence. Findings suggest that schools, practitioners, and policy makers are not meeting the needs of adolescents in regard to dating violence prevention and intervention. Prevention and intervention efforts could be improved by delivering education and services using language that adolescents find relevant. Findings also suggest that adolescents may benefit from prevention and intervention with gender specific components.

  13. Including non-public data and studies in systematic reviews and systematic maps.

    2017-02-01

    Systematic reviews and maps should be based on the best available evidence, and reviewers should make all reasonable efforts to source and include potentially relevant studies. However, reviewers may not be able to consider all existing evidence, since some data and studies may not be publicly available. Including non-public studies in reviews provides a valuable opportunity to increase systematic review/map comprehensiveness, potentially mitigating negative impacts of publication bias. Studies may be non-public for many reasons: some may still be in the process of being published (publication can take a long time); some may not be published due to author/publisher restrictions; publication bias may make it difficult to publish non-significant or negative results. Here, we consider what forms these non-public studies may take and the implications of including them in systematic reviews and maps. Reviewers should carefully consider the advantages and disadvantages of including non-public studies, weighing risks of bias against benefits of increased comprehensiveness. As with all systematic reviews and maps, reviewers must be transparent about methods used to obtain data and avoid risks of bias in their synthesis. We make tentative suggestions for reviewers in situations where non-public data may be present in an evidence base. Copyright © 2016 Elsevier Ltd. All rights reserved.

  14. Costs of decommissioning nuclear power plants as reported to the public to date

    International Nuclear Information System (INIS)

    Strasma, J.D.

    1982-01-01

    This paper attempts to determine what information has been available to the public, in the United States, concerning the cost of decommissioning nuclear power plants. The search was conducted in the Television News Index and Abstracts, in the annual indexes to The Reader's Digest, and in two computer-based bibliographic retrieval systems, Lockheed's DIALOG Magazine Index and the New York Times Information Bank. Fewer than ten articles appeared in widely read places, with none at all in the Reader's Digest and none on the evening TV news, from 1974 to date. The cost of decommissioning nuclear power plants was reported in various ways, with a wide range of estimates and relatively little actual experience. Costs were given in dollars of different years, in percentages of construction costs, in cost per KWH as per month to the consumer, etc., making the range of reported costs seem even wider than it really was. It is not surprising that the public fears that decommissioning costs will be alarmingly high. The public debate on energy policy might be more rational with better information on decommissioning costs. 16 references

  17. Towards a Comprehensive and Up-To-Date Institutional Repository: Development of a Publications Tracking Process

    KAUST Repository

    Baessa, Mohamed

    2016-06-15

    As our repository matured we found that a concerted effort was needed to establish it as a resource that institutional stakeholders knew they could turn to for reliable information about the research outputs produced by researchers affiliated with or funded by our institution. The initial impetus for this project was the adoption of an institutional open access policy, which necessitated a process to track the publications of institutional authors, deposit items with applicable open access licenses, and notify authors when an accepted manuscript was needed. To support this process we developed a local publications tracking system independent of our hosted DSpace repository that regularly queries publisher and indexer APIs for new publications, checks for relevant permissions policies, identifies institutional authors and helps us send manuscript request emails. We also harvested records for past items and modified our repository to accommodate metadata-only records. The success of these tracking and harvesting services in making our repository comprehensive and up-to-date has allowed us to rely on our repository as the key source of publications information for additional integrations that update ORCID records with publication information, populate a PlumX metrics dashboard and, most recently, support the implementation of a current research information system (CRIS).

  4. Quaternary dating methods

    International Nuclear Information System (INIS)

    Mahaney, W.C.

    1984-01-01

    The papers in this book cover absolute, relative and multiple dating methods, and have been written by specialists from a number of different earth sciences disciplines - their common interest being the dating of geological materials within the Quaternary. Papers on absolute dating methods discuss radiocarbon, uranium-series, potassium argon, 40 Ar/ 39 Ar, paleomagnetic, obsidian hydration, thermoluminescence, amino acid racemization, tree rings, and lichenometric techniques. Those on relative dating include discussions on various geomorphic relative age indicators such as drainage density changes, hypsometric integrals, bifurcation ratios, stream junction angles, spur morphology, hillslope geometry, and till sheet characteristics. The papers on multiple dating cite examples from the Rocky Mountains, Australia, Lake Agassiz Basin, and the Southern Andes. Also included is the panel discussion which reviews and assesses the information presented, and a field trip guide which discusses the sequences of Wisconian tills and interlayered lacustrine and fluvial sediments.

    2007-01-01

    Women in Nuclear-Korea (WINK) surveyed the public understanding on various energy resources in early September 2006 to offer the result for establishment of the nuclear communication policy. The reason why this survey includes other energy resources is because the previous works are only limited on nuclear energy, and also aimed to know the public's opinion on the present communication skill of nuclear energy for the public understanding. The present study is purposed of having data how public understands nuclear energy compared to other energies, such as fossil fuels, hydro power, and other sustainable energies. The data obtained from this survey have shown different results according to the responded group; age, gender, residential area, etc. Responded numbers are more than 2,000 of general public and university students. The survey result shows that nuclear understanding is more negative in women than in men, and is more negative in young than older age

    1996-01-01

    The absolute dating (radiocarbon, 14 C dating) and relative dating of Pringapus and Gondosuli temples in Temanggung regency (district) of Central Java Province have been carried out. The field sampling was done especially with the purpose to obtain vertical data, so that excavation method was adopted in the case. The main data were the ecofacts of organic habitation such as bones, woods, charcoals, shells, and paper artefacts. The artefacts data were used as a comparison. The comparative data analysis were conducted at Yogyakarta archaeological Department Laboratory, thus included dating of artefacts which were performed according to archaeological analysis procedures, generally based on the attributes attached to the artefacts, whereas the absolute dating of charcoal samples were performed in the Radiocarbon Dating Laboratory at Yogyakarta Nuclear Research Centre. Based on the relative dating of epigraphy content on the andesit rock from Gondosuli Temple which showed the year of 754 Saka or 832 AD, the Pringapus Temple was estimated to be built in the 850 AD. According to the absolute dating (Radiocarbon Dating with delta 13 C and tree ring corrections) the age for Gondosuli temple based on GDS/LU-2/Spit-7 samples is (384 -602) AD and from GDS/LU-2/Spit-8 = (452 - 652) AD. With these significant differences in the results obtained, it can be concluded that culture environment where the sample were collected already existed before the temple was built. Further investigation is still required

  9. Physical dating violence victimization in college women in Chile.

    Lehrer, Jocelyn A; Lehrer, Evelyn L; Zhao, Zhenxiang

    2010-05-01

    There are no published studies on physical dating violence in college students in Chile, and campuses across the country currently lack systematized programs to prevent or respond to this public health problem. This is the first study to examine prevalence and predictors of physical dating violence victimization with a sample of female college students in Chile. A closed-ended questionnaire was administered to students enrolled in general education courses at a major public university. The prevalence of women's physical dating violence victimization was calculated, and generalized ordered logit models were used to estimate risk factors for such victimization (n = 441). Ancillary analyses examined associations of dating violence victimization with experiences of unwanted sexual contact and forced condom nonuse. Approximately 21% of subjects reported one or more incidents of physical dating violence not involving physical injury since age 14, and another 5% reported at least one incident resulting in physical injury during this time period. Risk factors identified in five sequential models were sexual abuse and witnessing of domestic violence in childhood, low parental education, residence away from the parental home, urban residence, and having had sexual intercourse. Maternal employment and religious participation had protective effects. Dating violence victimization was found to be significantly associated with experiences of unwanted sexual contact and forced condom nonuse. The study findings show a high prevalence of physical dating violence, strong associations between several sociodemographic factors and dating violence, and links between dating violence and sexual/reproductive risk. Our results indicate a need to expand attention to this public health problem in Chile as well as other developing countries, where research and prevention/response initiatives have generally been similarly limited. The findings also have important implications for the content of

  10. The influence of online posting dates on the bibliometric indicators of scientific articles

    Directory of Open Access Journals (Sweden)

    Mercedes Echeverría

    2017-09-01

    Full Text Available This article analyses the difference in timing between the online availability of articles and their corresponding print publication and how it affects two bibliometric indicators: Journal Impact Factor (JIF and Immediacy Index. This research examined 18,526 articles, the complete collection of articles and reviews published by a set of 61 journals on Urology and Nephrology in 2013 and 2014. The findings suggest that Advance Online Publication (AOP accelerates the citation of articles and affects the JIF and Immediacy Index values. Regarding the JIF values, the comparison between journals with or without AOP showed statistically significant differences (P=0.001, Mann-Whitney U test. The Spearman’s correlation between the JIF and the median online-to-print publication delay was not statistically significant. As to the Immediacy Index, a significant Spearman’s correlation (rs=0.280, P=0.029 was found regarding the median online-to-print publication delays for journals published in 2014, although no statistically significant correlation was found for those published in 2013. Most journals examined (n=52 out of 61 published their articles in AOP. The analysis also showed different publisher practices: eight journals did not include the online posting dates in the full-text and nine journals published articles showing two different online posting dates--the date provided on the journal website and another provided by Elsevier’s Science Direct. These practices suggest the need for transparency and standardization of the AOP dates of scientific articles for calculating bibliometric indicators for journals.

  11. An independently dated 2000-yr volcanic record from Law Dome, East Antarctica, including a new perspective on the dating of the 1450s CE eruption of Kuwae, Vanuatu

    Directory of Open Access Journals (Sweden)

    C. T. Plummer

    2012-11-01

    Full Text Available Volcanic eruptions are an important cause of natural climate variability. In order to improve the accuracy of climate models, precise dating and magnitude of the climatic effects of past volcanism are necessary. Here we present a 2000-yr record of Southern Hemisphere volcanism recorded in ice cores from the high accumulation Law Dome site, East Antarctica. The ice cores were analysed for a suite of chemistry signals and are independently dated via annual layer counting, with 11 ambiguous years at 23 BCE, which has presently the lowest error of all published long Antarctic ice cores. Independently dated records are important to avoid circular dating where volcanic signatures are assigned a date from some external information rather than using the date it is found in the ice core. Forty-five volcanic events have been identified using the sulphate chemistry of the Law Dome record. The low dating error and comparison with the NGRIP (North Greenland Ice Core Project volcanic records (on the GICC05 timescale suggest Law Dome is the most accurately dated Antarctic volcanic dataset, which will improve the dating of individual volcanic events and potentially allow better correlation between ice core records, leading to improvements in global volcanic forcing datasets. One of the most important volcanic events of the last two millennia is the large 1450s CE event, usually assigned to the eruption of Kuwae, Vanuatu. In this study, we review the evidence surrounding the presently accepted date for this event, and make the case that two separate eruptions have caused confusion in the assignment of this event. Volcanic sulphate deposition estimates are important for modelling the climatic response to eruptions. The largest volcanic sulphate events in our record are dated at 1458 CE (Kuwae?, Vanuatu, 1257 and 422 CE (unidentified.

    In this paper, we used SVM in classifying various types of dates using their images. Dates have interesting different characteristics that can be valuable to distinguish and determine a particular date type. These characteristics include shape, texture, and color. A system that achieves 100% accuracy was built to classify the dates which can be eatable and cannot be eatable. The built system helps the food industry and customer in classifying dates depending on specific quality measures giving best performance with specific type of dates.

    The aim of this paper is to assess the possible consequences of adolescent physical, emotional and sexual dating violence through a review of the literature on the topic. An electronic search of major biomedical bibliographic databases (Pubmed, ISI, PsycINFO) was used to retrieve articles providing information on the prevalence rates, risk factors, associated consequences and possible preventive measures for adolescent dating violence across different populations. Currently, there have been few longitudinal studies conducted to identify potential risk factors for entering a violent dating relationship in adolescence. Risky behaviors such as early sexual intercourse may predispose someone for victimization. Dating violence itself is also a predictor of future dating violence. Adolescent dating violence was associated with an increase in other violence-related behaviors, substance use, depression, poorer educational outcomes, posttraumatic stress, unhealthy weight control and risky sexual behavior. The association between adolescent dating violence and an increase in suicidal behavior is a major public health concern. Future research should focus on longitudinal studies so that a causal relationship between dating violence and suicidality may be better understood.

    This study determined prevalence and correlates of physical dating violence (victimization or aggression) among male and female youth with alcohol misuse and seeking emergency department (ED) care. Patients age 14-20 seeking care at a single large university-based ED completed a computerized, self-administered, cross-sectional survey. Measures included demographics, alcohol and substance use, mental health problems, health service use, peer influences, parent support, and community involvement. Bivariate and multivariate regression assessed physical dating violence correlates. Among 842 male and female youth seeking ED care who screened positive for alcohol misuse, 22.3% (n=188) reported dating violence in the past year. Multivariate analyses showed variables associated with dating violence were female gender (AOR 2.17, CI 1.46-3.22), Caucasian race (AOR 0.59, CI 0.37-0.93), receipt of public assistance (AOR 1.82, CI 1.16-2.87), AUDIT Score (AOR 1.06, CI 1.02-1.10), older age of drinking onset (AOR 0.86, CI 0.77-0.96), suicidal ideation or attempt (AOR 1.95, CI 1.13-3.37), frequency of ED visits (AOR 1.22, CI 1.05-1.46), negative peer influences (AOR 1.05, CI 1.01-1.10), and positive peer influences (AOR 0.86, CI 0.80-0.93). Nearly 1 in 4 youth with alcohol misuse seeking ED care report dating violence. Key correlates of dating violence included alcohol use severity, suicidal ideation, ED services, and peer influences. Evidence-based dating violence interventions addressing these correlates are needed for youth with alcohol misuse seeking ED care. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    "Ethics" is used as a label for a new kind of expertise in the field of science and technology. At the same time, it is not clear what ethical expertise consists in and what its political status in modern democracies can be. Starting from the "participatory turn" in recent social research and policy, we will argue that bioethical reasoning has to include public views of and attitudes towards biomedicine. We will sketch the outlines of a bioethical conception of "public understanding of ethics," addressing three different issues: (a) the methodological relevance of moral questions and problems raised by lay persons in everyday life regarding biomedicine and technology, (b) the normative relevance of such lay moralities for the justification of ethical decisions, and (c) the necessity of public deliberation in this context. Finally, we draw conclusions in view of the concepts and methods such a conception of "public understanding of ethics" should employ.

    The Community Assessment Tool (CAT) for Public Health Emergencies Including Pandemic Influenza (hereafter referred to as the CAT) was developed as a result of feedback received from several communities. These communities participated in workshops focused on influenza pandemic planning and response. The 2008 through 2011 workshops were sponsored by the Centers for Disease Control and Prevention (CDC). Feedback during those workshops indicated the need for a tool that a community can use to assess its readiness for a disaster - readiness from a total healthcare perspective, not just hospitals, but the whole healthcare system. The CAT intends to do just that - help strengthen existing preparedness plans by allowing the healthcare system and other agencies to work together during an influenza pandemic. It helps reveal each core agency partners (sectors) capabilities and resources, and highlights cases of the same vendors being used for resource supplies (e.g., personal protective equipment [PPE] and oxygen) by the partners (e.g., public health departments, clinics, or hospitals). The CAT also addresses gaps in the community's capabilities or potential shortages in resources. This tool has been reviewed by a variety of key subject matter experts from federal, state, and local agencies and organizations. It also has been piloted with various communities that consist of different population sizes, to include large urban to small rural communities.

  6. Bomb pulse radiocarbon dating

    Modern forensic science has to deal not only with homicides and other traditional crimes but also with more global threats such as the smuggling of nuclear materials, clandestine production of weapons of mass destruction, stockpiling of illicit drugs by state controlled groups and war crimes. Forensic applications have always benefited from the use of advanced analytical tools that can characterize materials found at crime scenes. In this paper we will discuss the use of accelerator mass spectrometry (AMS) as an ultrasensitive tool for the crime laboratories of the third millennium. An important objective in forensic science is to order past events chronologically by analysing materials associated with criminal actions. Radiocarbon dating is known to the general public for its application to historical and prehistorical investigations. Examples of forensic significance include the assassination of the Inca Atahualpa by Francisco Pizarro in the early 1530s, the possible murder of the Tyrolean Ice Man (Oetzi) 5300 years ago and the analysis of the burial cloths allegedly associated with the crucifixion of Jesus Christ . Recent murders, including those associated with war crimes in the Balkans during the 1990s, can be studied using 14 C bomb pulse dating. This method has other forensic applications, including investigation of frauds related to food and wine counterfeiting, dating of opium crops and dating of substances used in biological warfare. AMS extends the applicability of the radiocarbon method, allowing the analysis of 14 C in submilligram organic samples. Specific molecular compounds extracted from bones, hair, skin and other carbon bearing substances of forensic significance can now be dated, enhancing the sensitivity and reliability of chronological determinations. AMS can also be used to analyse rare actinide isotopes released into the environment during the clandestine production of nuclear weapons or associated with the smuggling of nuclear materials. In

  10. Dating Violence in Mexico College Students: A Review

    Directory of Open Access Journals (Sweden)

    2013-06-01

    Full Text Available Dating violence in Mexico is a serious problem because 76% of young Mexicans have suffered psychological violence, 15% have suffered physical violence and 16.5% have suffered sexual violence (Mexican Youth Institute, 2008. Therefore it has been given increasing attention to the study of this phenomenon in numerous researches. Knowing the characteristics of this production would allow to consolidate or to open up new research lines, so this narrative review discusses the main methodological characteristics of research on dating violence in Mexican university students. It was included twenty scientific researches published by Mexicans and foreigners researchers between 2002 and 2012 in scientific journals or presented at scientific conferences, with samples consisting of Mexican university students aged between 18 and 25 years. The search was conducted in specialized databases such as Dialnet, Google Scholar, Psicodoc, Psycinfo, Redalyc and Scirus. The results show that 75% of the studies were quantitative designs, 100% was cross-sectional design and 85% had nonrandom sample. 95% of the samples were formed by students from public universities and 15% used an internationally validated questionnaire and controlled social desirability of responses. It concludes the need for more studies with mixed, dyadic or longitudinal designs, but with samples randomly selected from public and private universities. The need of control of social desirability of responses and the implementation of validated questionnaires to allow comparisons between results.

  11. Nonreciprocal and Reciprocal Dating Violence and Injury Occurrence among Urban Youth

    Directory of Open Access Journals (Sweden)

    Swahn, Monica H

    2010-08-01

    Full Text Available Objective: Dating violence is a significant health problem among youth that leads to adverse health outcomes, including injuries. Reciprocal violence (perpetrated by both partners is associated with increased injury in adults, but very little is known about the prevalence and context for reciprocal violence, as well as injury rates, among youth. We sought to determine the prevalence and scope of reciprocal dating violence and injury occurrence among urban youth in a high-risk community. Methods: Analyses were based on data from the Youth Violence Survey, conducted in 2004, and administered to over 80% of public school students in grades 7, 9, 11, and 12 (N=4,131 in a high-risk, urban school district. The current analyses were restricted to those who reported dating in the past year and who also reported any dating violence (n=1,158. Dating violence was categorized as reciprocal (the participant reported both violence perpetration and victimization and non-reciprocal (the participant report either violence perpetration or victimization, but not both. Results: Dating violence reciprocity varied by sex. Girls who reported any dating violence were more likely to report reciprocal dating violence (50.4% than were boys (38.9%. However, reciprocity did not vary by race/ethnicity or grade level. Reciprocal dating violence was more common among participants who reported more frequent violence experiences. Reciprocal violence was also associated with greater injury occurrences relative to non-reciprocal relationships (10.1% versus 1.2%. Conclusion: Reciprocal dating violence is common among adolescents and leads more often to injury outcomes. In particular, relationships in which boys report reciprocal violence against their partner appear to lead to more frequent injury occurrences. These findings underscore the importance of addressing dating violence and factors that increase risk for reciprocal violence and therefore exacerbate injury occurrence

  16. Isotopic and molecular fractionation in combustion; three routes to molecular marker validation, including direct molecular 'dating' (GC/AMS)

    Science.gov (United States)

    Currie, L. A.; Klouda, G. A.; Benner, B. A.; Garrity, K.; Eglinton, T. I.

    The identification of unique isotopic, elemental, and molecular markers for sources of combustion aerosol has growing practical importance because of the potential effects of fine particle aerosol on health, visibility and global climate. It is urgent, therefore, that substantial efforts be directed toward the validation of assumptions involving the use of such tracers for source apportionment. We describe here three independent routes toward carbonaceous aerosol molecular marker identification and validation: (1) tracer regression and multivariate statistical techniques applied to field measurements of mixed source, carbonaceous aerosols; (2) a new development in aerosol 14C metrology: direct, pure compound accelerator mass spectrometry (AMS) by off-line GC/AMS ('molecular dating'); and (3) direct observation of isotopic and molecular source emissions during controlled laboratory combustion of specific fuels. Findings from the combined studies include: independent support for benzo( ghi)perylene as a motor vehicle tracer from the first (statistical) and second (direct 'dating') studies; a new indication, from the third (controlled combustion) study, of a relation between 13C isotopic fractionation and PAH molecular fractionation, also linked with fuel and stage of combustion; and quantitative data showing the influence of both fuel type and combustion conditions on the yields of such species as elemental carbon and PAH, reinforcing the importance of exercising caution when applying presumed conservative elemental or organic tracers to fossil or biomass burning field data as in the first study.

  17. Bidirectional Relations Between Dating Violence Victimization and Substance Use in a Diverse Sample of Early Adolescents.

    2017-09-01

    Substance use and dating violence victimization are common in adolescence and represent significant public health concerns. Although theoretical accounts suggest a bidirectional association between substance use and victimization within dating relationships, this has not been tested during early adolescence. Thus, the current study examined bidirectional associations between physical and psychological dating violence victimization and substance use across 6 months among an ethnically diverse sample of early adolescents. Sex was also examined as a moderator. Participants included two cohorts of sixth graders from 37 schools who were in dating relationships in the last 3 months at Wave 1, in the fall of sixth grade, and 6 months later at Wave 2, in the spring of sixth grade ( n = 2,022; 43% female; 55% Black, 17% Latino/a, 16% White, 9% as multiracial, and 3% as another race/ethnicity). Students reported on the frequency of dating violence in the past 3 months and substance use in the past 30 days. Multilevel models, with students at Level 1 and classes (i.e., clusters of students in the same cohort at the same school; n = 74) at Level 2, tested hypotheses that positive reciprocal relations between physical and psychological dating violence victimization and substance use would be found over time, and that relations would be stronger for girls than boys. Sex, race/ethnicity, and family structure variables were included as Level 1 covariates; intervention condition and neighborhood concentrated disadvantage were included as Level 2 covariates. Results showed that higher levels of physical dating violence victimization at Wave 1 predicted increased substance use at Wave 2. Higher levels of substance use at Wave 1 predicted increased physical and psychological dating violence victimization at Wave 2. Findings highlight the importance of prevention efforts for dating violence and substance use early in adolescence.

  18. Potassium-argon dating in archaeology

    McDougall, I. (Australian National Univ., Canberra (Australia). Research School of Earth Sciences)

    1990-01-01

    The potassium-argon (K-Ar) isotopic dating method can provide precise and accurate numerical ages on suitable rocks, especially igneous rocks, over a wide range of age from less than 100,000 years old, with no older limit. Together with its variants, the {sup 40}Ar/{sup 39}Ar technique, the K-Ar method is very useful for the numerical age calibration of stratigraphic sequences, including those containing archaeological or fossil material, in cases where appropriate rocks for dating are present. This brief review of the basis of the K-Ar dating method and the underlying assumptions, concludes with an example of its application to the Plio-Pleistocene stratigraphic sequence in the Turkana Basin, northern Kenya. By dating alkali feldspars separated from pumice blocks in tuffaceous beds, excellent age control has been obtained for the wealth of vertebrate fossils, including hominids, as well as archaeological materials that has been found in the sequence.

    The new curriculum of physics of the upper forms in French grammar schools includes a part dedicated to ''nuclear transformations''. One of the applications most often considered in manuals is isotopic dating and generally several methods are explained to pupils: carbon 14 dating, potassium-argon dating (used for dating ancient lava layers) and uranium-thorium dating (used for dating corals). The author reviews with a critical eye the content of manuals and laments through concrete examples the lack of exactness and accuracy of some presentations. (A.C.)

    2008-11-01

    Accurate and precise dating is vital to our understanding of the Middle to Upper Paleolithic transition. There are, however, a number of uncertainties in the chronologies currently available for this period. We attempt to examine these uncertainties by utilizing a number of recent developments in the field. These include: the precise dating of the Campanian Ignimbrite (CI) tephra by 40Ar/39Ar; the tracing of this tephra to a number of deposits that are radiocarbon dated; the publication of revised radiocarbon calibration data for the period, showing a much better convergence with other available data than during the recent IntCal comparison; and a layer-counted ice-core chronology extending beyond 40,000cal BP. Our data comparisons suggest that a reasonable overall convergence between calibrated radiocarbon ages and calendar dates is possible using the new curves. Additionally, we suggest that charcoal-based radiocarbon ages, as well as bone-based radiocarbon determinations, require cautious interpretation in this period. Potentially, these issues extend far beyond the sites in this study and should be of serious concern to archaeologists studying the Middle to Upper Paleolithic. We conclude by outlining a strategy for moving the science forward by a closer integration of archaeology, chronology, and stratigraphy.

    2006-01-01

    The methods that can be used for the direct dating of human remains comprise of radiocarbon, U-series, electron spin resonance (ESR), and amino acid racemization (AAR). This review gives an introduction to these methods in the context of dating human bones and teeth. Recent advances in ultrafiltration techniques have expanded the dating range of radiocarbon. It now seems feasible to reliably date bones up to 55,000 years. New developments in laser ablation mass spectrometry permit the in situ analysis of U-series isotopes, thus providing a rapid and virtually non-destructive dating method back to about 300,000 years. This is of particular importance when used in conjunction with non-destructive ESR analysis. New approaches in AAR analysis may lead to a renaissance of this method. The potential and present limitations of these direct dating techniques are discussed for sites relevant to the reconstruction of modern human evolution, including Florisbad, Border Cave, Tabun, Skhul, Qafzeh, Vindija, Banyoles, and Lake Mungo.

These communities participated in workshops focused on influenza pandemic planning and response. The 2008 through 2011 workshops were sponsored by the Centers for Disease Control and Prevention (CDC). Feedback during those workshops indicated the need for a tool that a community can use to assess its readiness for a disaster—readiness from a total healthcare perspective, not just hospitals, but the whole healthcare system. The CAT intends to do just that—help strengthen existing preparedness plans by allowing the healthcare system and other agencies to work together during an influenza pandemic. It helps reveal each core agency partners' (sectors) capabilities and resources, and highlights cases of the same vendors being used for resource supplies (e.g., personal protective equipment [PPE] and oxygen) by the partners (e.g., public health departments, clinics, or hospitals). The CAT also addresses gaps in the community's capabilities or potential shortages in resources. While the purpose of the CAT is to further prepare the community for an influenza pandemic, its framework is an extension of the traditional all-hazards approach to planning and preparedness. As such, the information gathered by the tool is useful in preparation for most widespread public health emergencies. This tool is primarily intended for use by those involved in healthcare emergency preparedness (e.g., community planners, community disaster preparedness coordinators, 9-1-1 directors, hospital emergency preparedness coordinators). It is divided into sections based on the core agency partners, which may be involved in the community's influenza pandemic influenza response.

  6. A Protection Motivation Theory application to date rape education.

    Singh, Shweta; Orwat, John; Grossman, Susan

    2011-12-01

    Date rape risk communication is a key component of education-based Date Rape Prevention Programs, common across colleges. In such programs, risk assessment in date rape is approached cautiously in order to avoid a tone of "victim blaming." Since it is important in the assessment of any risk to understand the surrounding social context of the risky situation and the individual's unique relationship with that social context, this study examines Protection Motivation Theory as it applies to handling the risk of date rape without victim blaming. The paper links individual personality and social contexts with risk communication. The study sample comprised 367 undergraduate women enrolled in a large Southern Public University. The study examines the relationships between dating activity, social competency, and type of information provided with the dependents variables of date rape related protection behavior (intent), belief, and knowledge. A factorial multiple analysis of covariance analysis found that the dependent variables had a significant relationship with aspects of social competency and dating activity. The exposure to varying information about date rape was not significantly related to the dependent variables of date rape-related protection behavior (intent), belief, and knowledge. The identification of social competency and dating activity status as protective factors in this study makes a significant contribution to the practice and research efforts in date rape education.

    Dating violence is a serious and prevalent public health problem that is associated with numerous negative physical and psychological health outcomes, and yet there has been limited evaluation of prevention programs on college campuses. A recent innovation in campus prevention focuses on mobilizing bystanders to take action. To date, bystander programs have mainly been compared with no treatment control groups raising questions about what value is added to dating violence prevention by focusing on bystanders. This study compared a single 90-min bystander education program for dating violence prevention with a traditional awareness education program, as well as with a no education control group. Using a quasi-experimental pre-test/post-test design with follow-up at 2 months, a sample of predominately freshmen college students was randomized to either the bystander (n = 369) or traditional awareness (n = 376) dating violence education program. A non-randomized control group of freshmen students who did not receive any education were also surveyed (n = 224). Students completed measures of attitudes, including rape myth acceptance, bystander efficacy, and intent to help as well as behavioral measures related to bystander action and victimization. Results showed that the bystander education program was more effective at changing attitudes, beliefs, efficacy, intentions, and self-reported behaviors compared with the traditional awareness education program. Both programs were significantly more effective than no education. The findings of this study have important implications for future dating violence prevention educational programming, emphasizing the value of bystander education programs for primary dating violence prevention among college students. © The Author(s) 2016.

    Although evidence suggests that bystander prevention programs are promising interventions for decreasing sexual violence and dating violence on college campuses, there have been no studies to date evaluating moderators of bystander program effectiveness. The current study evaluates whether different demographic characteristics, attitudes, knowledge, and behaviors at pretest predict change over a 6-month follow-up for students who participated in a bystander prevention program. Participants in the three assessments (pretest, posttest, 6-month follow-up) included 296 college students who were mandated to attend a bystander program during their first year orientation. Analyses showed that with few exceptions, the bystander program worked best for students who were most at risk given their pretest demographics and levels of attitudes condoning dating violence and sexual violence, bystander efficacy, and bystander behaviors. Results are discussed in terms of suggestions for future research. © 2014 Society for Public Health Education.

    Dating violence is a serious public health issue that needs further understanding in terms of risk factors that may be involved in it. The main goal of this study was to test a mediational model of dating violence risk factors. The sample was composed of 477 secondary and college students from Spain (59% females). A dynamic developmental explanatory model considering aggressiveness, insecure attachment, interparental conflict, and peer dating violence was tested using a multigroup structural equation model. Aggressiveness partially mediated the relation between anxious attachment and dating violence and fully mediated the association between interparental conflict resolution and dating violence. Furthermore, perceived peer dating violence was a direct predictor of dating violence. Implications for prevention and intervention plans are discussed. © 2017 The Authors.

    In an attempt to provide a chronology for Indian archaeological sites, an extensive pottery dating programme was initiated during 1978-1979. So far we have provided a chronology for seven important Indian archaeological sites. The dated cultures include: 1) the Ochre Colour Ware culture, 2) the Pre-Harappan culture, 3) the megalithic culture and 4) the Painted Grey Ware culture. A complete survey of recently measured TL dates are presented in a model format similar to that used in Radiocarbon. (author)

  14. Double the dates and go for Bayes - Impacts of model choice, dating density and quality on chronologies

    Science.gov (United States)

    Blaauw, Maarten; Christen, J. Andrés; Bennett, K. D.; Reimer, Paula J.

    2018-05-01

    Reliable chronologies are essential for most Quaternary studies, but little is known about how age-depth model choice, as well as dating density and quality, affect the precision and accuracy of chronologies. A meta-analysis suggests that most existing late-Quaternary studies contain fewer than one date per millennium, and provide millennial-scale precision at best. We use existing and simulated sediment cores to estimate what dating density and quality are required to obtain accurate chronologies at a desired precision. For many sites, a doubling in dating density would significantly improve chronologies and thus their value for reconstructing and interpreting past environmental changes. Commonly used classical age-depth models stop becoming more precise after a minimum dating density is reached, but the precision of Bayesian age-depth models which take advantage of chronological ordering continues to improve with more dates. Our simulations show that classical age-depth models severely underestimate uncertainty and are inaccurate at low dating densities, and also perform poorly at high dating densities. On the other hand, Bayesian age-depth models provide more realistic precision estimates, including at low to average dating densities, and are much more robust against dating scatter and outliers. Indeed, Bayesian age-depth models outperform classical ones at all tested dating densities, qualities and time-scales. We recommend that chronologies should be produced using Bayesian age-depth models taking into account chronological ordering and based on a minimum of 2 dates per millennium.

    A novel protocol for the commercial production of date palm through micropropagation is presented. This protocol includes the use of a semisolid medium alternation or in combination with a temporary immersion system (TIS, Plantform bioreactor) in date palm micropropagation. The use of the Plantform bioreactor for date palm results in an improved multiplication rate, reduced micropropagation time, and improved weaning success. It also reduces the cost of saleable units and thus improves economic return for commercial micropropagation. The use of the Plantform bioreactor successfully addresses other hindrances that can occur during the scale-up of date palm micropropagation, including asynchrony of somatic embryos, limited maturation of somatic embryos, and highly variable germination frequencies of embryos.

  17. Dating fossil opal phytoliths

    International Nuclear Information System (INIS)

    Lentfer, C.; Boyd, B.; Torrence, R.

    1999-01-01

    Full text: Opal phytoliths are microscopic silica bodies formed by the precipitation of hydrated silica dioxide (SiO 2 nH 2 0) in, around and between cell walls. They are relatively resistant to degradation in most environments and thus, can occur in large quantities in palaeosediments. Consequently, they are valuable tools for environmental reconstruction. Furthermore, phytoliths are often the only recoverable organic material in well oxidised sediments, the occluded carbon provides the opportunity for dating sediment whose ages have previously been difficult to determine, and thus, increase the potential for fine resolution determination of environmental change. This poster describes the results of an investigation assessing the viability of AMS radiocarbon dating of fossil phytolith inclusions using samples from Garua Island, West New Britain, PNG. Thirteen phytolith samples, isolated from sediments previously dated using tephrastratigraphy and C14 dating of macroremains of nutshells and wood charcoal, were used in the analysis. As a control measure, thirteen parallel samples of microscopic charcoal were also dated using AMS. The results show that the AMS dates for the microscopic charcoal samples are consistent with ages anticipated from the other dating methods, for all but one sample. However, the dates for eight of the thirteen phytolith samples are considerably younger than expected. This bias could be explained by several factors, including downwashing of phytolith through soils, bioturbation, carbon exchange through the siliceous matrix of the phytolith bodies, and contamination from extraneous sources of modern carbon retained in the samples. Research is currently focusing on the investigation of these issues and selected samples are in the process of being retreated with strong oxidising agents to clear contaminants prior to re-dating. Further to this, a full investigation of one profile with a long sequence is underway. High concentrations of

    Unconventional oil and gas extraction (UOGE) including fracking for shale gas is underway in North America on a large scale, and in Australia and some other countries. It is viewed as a major source of global energy needs by proponents. Critics consider fracking and UOGE an immediate and long-term threat to global, national, and regional public health and climate. Rarely have governments brought together relatively detailed assessments of direct and indirect public health risks associated with fracking and weighed these against potential benefits to inform a national debate on whether to pursue this energy route. The Scottish government has now done so in a wide-ranging consultation underpinned by a variety of reports on unconventional gas extraction including fracking. This paper analyses the Scottish government approach from inception to conclusion, and from procedures to outcomes. The reports commissioned by the Scottish government include a comprehensive review dedicated specifically to public health as well as reports on climate change, economic impacts, transport, geology, and decommissioning. All these reports are relevant to public health, and taken together offer a comprehensive review of existing evidence. The approach is unique globally when compared with UOGE assessments conducted in the USA, Australia, Canada, and England. The review process builds a useful evidence base although it is not without flaws. The process approach, if not the content, offers a framework that may have merits globally.

    Smartphone apps provide a new platform for entertainment, information distribution, and health promotion activities, as well as for dating and casual sexual encounters. Previous research has shown high acceptability of sexual health interventions via smartphone apps; however, sexual health promotion apps were infrequently downloaded and underused. Integrating sexual health promotion into established apps might be a more effective method. The objective of our study was to critically review popular sex-related apps and dating apps, in order to ascertain whether they contain any sexual health content. Part 1: In January 2015, we used the term "sexual" to search for free apps in the Apple iTunes store and Android Google Play store, and categorized the sexual health content of the 137 apps identified. Part 2: We used the term "dating" to search for free geosocial-networking apps in the Apple iTunes and Android Google Play stores. The apps were downloaded to test functionality and to determine whether they included sexual health content. Part 1: Of the 137 apps identified, 15 (11.0%) had sexual health content and 15 (11.0%) contained messages about sexual assault or violence. The majority of the apps did not contain any sexual health content. Part 2: We reviewed 60 dating apps: 44 (73%) targeting heterosexual users, 9 (15%) targeting men who have sex with men (MSM), 3 (5%) targeting lesbian women, and 4 (7%) for group dating. Only 9 dating apps contained sexual health content, of which 7 targeted MSM. The majority of sex-related apps and dating apps contained no sexual health content that could educate users about and remind them of their sexual risks. Sexual health practitioners and public health departments will need to work with app developers to promote sexual health within existing popular apps. For those apps that already contain sexual health messages, further study to investigate the effectiveness of the content is needed. ©Evelyn Tzu-Yen Huang, Henrietta

    Diabetic retinopathy (DR) is one of the leading causes of vision loss and blindness in Canada. Eye examinations play an important role in early detection. However, DR screening by optometrists is not always universally covered by public or private health insurance plans. This study assessed whether expanding public health coverage to include diabetic eye examinations for retinopathy by optometrists is cost-effective from the perspective of the health care system. We conducted a cost-utility analysis of extended coverage for diabetic eye examinations in Prince Edward Island to include examinations by optometrists, not currently publicly covered. We used a Markov chain to simulate disease burden based on eye examination rates and DR progression over a 30-year time horizon. Results were presented as an incremental cost per quality-adjusted life year (QALY) gained. A series of one-way and probabilistic sensitivity analyses were performed. Extending public health coverage to eye examinations by optometrists was associated with higher costs ($9,908,543.32) and improved QALYs (156,862.44), over 30 years, resulting in an incremental cost-effectiveness ratio of $1668.43/QALY gained. Sensitivity analysis showed that the most influential determinants of the results were the cost of optometric screening and selected utility scores. At the commonly used threshold of $50,000/QALY, the probability that the new policy was cost-effective was 99.99%. Extending public health coverage to eye examinations by optometrists is cost-effective based on a commonly used threshold of $50,000/QALY. Findings from this study can inform the decision to expand public-insured optometric services for patients with diabetes.

    Advances in technologies including development of smartphone features have contributed to the growth of mobile applications, including dating apps. However, online dating services can be misused. To support law enforcement investigations, a forensic taxonomy that provides a systematic classification of forensic artifacts from Windows Phone 8 (WP8) dating apps is presented in this study. The taxonomy has three categories, namely: Apps Categories, Artifacts Categories, and Data Partition Categories. This taxonomy is built based on the findings from a case study of 28 mobile dating apps, using mobile forensic tools. The dating app taxonomy can be used to inform future studies of dating and related apps, such as those from Android and iOS platforms. © 2018 American Academy of Forensic Sciences.

    1980-01-01

    Polyhalite, K 2 Ca 2 Mg(SO 4 ) 4 .2H 2 O, is an important mineral in many evaporites. Although its use for K-Ar dating has never been investigated, present results indicate that it is a very useful mineral for dating events ranging from the time of potash mineralization to any younger events which may have affected the evaporite. Five K-Ar dates on pure polyhalite, including two from included material and from beds distorted by the formation of a rubble chimney, yield dates between 198 and 216 Myp, in good agreement with Rb-Sr dates and the diagenetic age of the potash deposits from the same rocks. Two polyhalites mixed with sylvite gave lower dates, which is to be expected because of radiogenic 40 Ar loss from the sylvite phase. One polyhalite, formed after the intrusion of a 31 Myr lamprophyre dike, yielded 21 Myr. Collectively, the results indicate that pure polyhalite is satisfactory for K-Ar dating and may provide critical age information in studies of the geologic history of the evaporite sequences.

    2006-06-01

    Full Text Available As a consequence of continuous adaptation of public institutions to requirements of framing where they perform day by day, Public Management and Administration is behaving once and again as a “reinvented” discipline, aiming a new kind of rational, innovative public entities that focus their activities towards an effective achievement of their intended results and benefits. Concepts such as those of “efficiency”, “effectiveness”, “responsibility”, “organizational culture”, etc. are now not only applied to business disciplines, but also to Public Management and Administration. At this point, Marketing has proved to be an useful subject in PMA curricula, not only being in demand by students and syllabi designers, but also by experts in the public field. However, applying marketing techniques and procedures in the same way as used in private business is clearly nonsense. We must consider a proper “public marketing” or “public sector marketing” development. In this paper we debate on these issues, as well as present an overview into the situation of Spanish public universities offering PMA studies, just when they are facing the Bologna adaptation requirements. As a conclusion, some comments for reflection are suggested.

  3. A Moderator Model of Alcohol Use and Dating Aggression among Young Adults.

    Science.gov (United States)

    Collibee, Charlene; Furman, Wyndol

    2018-03-01

    Dating aggression has been identified as a priority public health concern. Although alcohol use is a known robust risk factor for dating aggression involvement, such usage is neither necessary nor sufficient for dating aggression involvement. As such, a growing topic of interest is a better understanding of when, and for whom, alcohol use increases risk. A theoretical moderator model posits that associations between alcohol use and dating aggression involvement vary depending on both background (e.g., psychopathology) and situational (e.g., relationship characteristics) risk factors. Alcohol use is thought to be more strongly associated with dating aggression in the context of these other risk factors. Using an intensive longitudinal design, we collected six waves of data spanning 6 months from 120 participants (60 females; M age W1 = 22.44). Alcohol use and relationship risk were both associated with increases in dating aggression involvement. Consistent with a moderator model, interactions emerged between alcohol use and relationship risk for subsequent dating aggression involvement. The findings underscore the importance of alcohol use and relationship risk for the development of intervention and prevention programs.

    Dating violence is a serious and prevalent problem on college campuses. Although there is a robust literature documenting that alcohol use is consistently associated with increased risk for perpetrating dating violence, little research has examined the role of cannabis in dating violence perpetration. With increasing legalisation of cannabis throughout the world, it is imperative to understand what role, if any, cannabis may play in the important public health problem of dating violence. In this commentary, we discuss the current state of the research on cannabis and dating violence and suggest avenues for additional research in this area. It is critical that we conduct methodologically sound research on the association between cannabis and dating violence so that we can understand what role, if any, cannabis exerts on this important problem.

    The carbon dates for the eruptions of Rangitoto and the occupation of Maori sites on Motutapu contain inconsistencies which are explicable only after the dates have been corrected to allow for the nature of the dating method. The only date which is reasonably established is a 14th or 15th century dating for the ash shower covering Motutapu. (auth.)

    Little is known about the extent of selective publication in contemporary oncology randomised controlled trials (RCTs) worldwide. This study aimed to evaluate the rates of publication and timely publication (within 24 months) for contemporary oncology RCTs from all over the world. We also investigated the trial characteristics associated with publication and timely publication. We identified all phase III oncology RCTs registered on ClinicalTrials.gov with a primary completion date between January 2008 and December 2012. We searched PubMed and EMBASE to identify publications. The final search date was 31 December 2015. Our primary outcome measure was the time to publication from the primary completion date to the date of primary publication in a peer-reviewed journal. We identified 598 completed oncology RCTs; overall, 398 (66.6%) had been published. For published trials, the median time to publication was 25 months (interquartile range, 16-37 months). Only 192 trials (32.1%) were published within 24 months. Timely publication was independently associated with trials completed late in 2012. Trials conducted in Asia and other regions were less likely to have timely publication, but trials conducted in different locations were all equally likely to be published. Industry- and NIH-funded trials were equally likely to be published timely or at any time after trial completion. Among 391 published trials with clear primary outcomes, there was a trend for timely publication of positive trials compared with negative trials. Despite the ethical obligations and societal expectations of disclosing findings promptly, oncology RCTs performed poorly. Copyright © 2016 Elsevier Ltd. All rights reserved.

  11. Dangerous quantities of radioactive material (D-values). Emergency preparedness and response. Publication date: August 2006

    International Nuclear Information System (INIS)

    2006-08-01

    Radioactive material is widely used in industry, medicine, education and agriculture. In addition, it occurs naturally. The health risk posed by these materials vary widely depending on many factors, the most important of which are the amount of the material involved and its physical and chemical form. Therefore, there is a need to identify the quantity and type of radioactive material for which emergency preparedness and other arrangements (e.g. security) are warrant due to the health risk they pose. The aim of this publication is to provide practical guidance for Member States on that quantity of radioactive material that may be considered dangerous. A dangerous quantity is that, which if uncontrolled, could be involved in a reasonable scenario resulting in the death of an exposed individual or a permanent injury, which decreases that person's quality of life. This publication is published as part of the IAEA Emergency Preparedness and Response Series. It supports several publications including: the IAEA Safety Requirements 'Preparedness and Response for a Nuclear or Radiological Emergency', IAEA Safety Standards Series No. GS-R-2. IAEA, Vienna (2002); IAEA Safety Guide 'Categorization of Radioactive Sources', IAEA Safety Standards Series No RS-G-1.9, IAEA, Vienna (2005) and IAEA Safety Guide 'Arrangements for Preparedness for a Nuclear or Radiological Emergency' IAEA Safety Standards Series No. GS-G-2.1, IAEA, Vienna (2006). The procedures and data in this publication have been prepared with due attention to accuracy. However, as part of the review process, they undergo ongoing quality assurance checks. Comments are welcome and, following a period that will allow for a more extensive review, the IAEA may revise this publication as part of the process of continuous improvement. The publication uses a number of exposure scenarios, risk models and dosimetric data, which could be used during the response to nuclear or radiological emergency or other purposes

    Breeding of date palm is complicated because of its long life cycle and heterozygous nature. Sexual propagation of date palm does not produce true-to-type plants. Sex of date palms cannot be identified until the first flowering stage. Molecular markers such as random amplified polymorphic DNA (RAPD), sequence-characterized amplified regions (SCAR), and simple sequence repeats (SSR) have successfully been used to identify the sex-linked loci in the plant genome and to isolate the corresponding genes. This chapter highlights the use of three molecular markers including RAPD, SCAR, and SSR to identify the gender of date palm seedlings.

    Date fruit has served as a staple food in the Arab world for centuries. Worldwide production of date fruit has increased almost threefold over the last 40 years, reaching 7.68 million tons in 2010. Date fruit can provide many essential nutrients and potential health benefits to the consumer. Date fruit goes through four ripening stages named kimri, khalal, rutab and tamer. The main chemical components of date fruit include carbohydrates, dietary fibre, enzymes, protein, fat, minerals, vitamins, phenolic acids and carotenoids. The chemical composition of date fruit varies according to ripening stage, cultivar, growing environment, postharvest conditions, etc. The nutritional and medicinal activities of date fruit are related to its chemical composition. Many studies have shown that date fruit has antioxidant, antimutagenic, anti-inflammatory, gastroprotective, hepatoprotective, nephroprotective, anticancer and immunostimulant activities. Various date fruit-based products such as date syrup, date paste, date juice and their derived products are available. Date by-products can be used as raw materials for the production of value-added products such as organic acids, exopolysaccharides, antibiotics, date-flavoured probiotic-fermented dairy produce, bakery yeasts, etc. In this paper the chemical composition and nutritional and medicinal values of date fruit as well as date fruit-based products are reviewed. © 2013 Society of Chemical Industry.

  14. Luminescence dating

    2013-01-01

    The luminescence techniques have evolved over the last 40 years to a powerful dating instrument in archaeology and geoscience. Depending on how the luminescence is stimulated, one distinguishes the phenomena of thermoluminescence (TL), optically stimulated luminescence (OSL) and infrared stimulated luminescence (IRSL). Each of these phenomena has its specific potential for dating various archaeological materials in the time range from medieval back to palaeolithic periods, or, speaking in geological terms, for dating of Holocene and late Pleistocene objects. The OSL and IRSL techniques are sometimes treated together as 'optical dating'. The luminescence techniques differ from other major dating techniques, such as 14 C, essentially by their applicability to inorganic materials, their wide age-range from about 100 years to more than 100,000 years and the kind of datable events which are the last exposure to heat or to light.

    2012-01-01

    Bullying is the use of power and aggression to control and distress another. In this paper, we review research to explore whether the lessons learned in bullying provide a stepping stone to aggressive behavior in dating relationships. We start by considering definitions and a relationship framework with which to understand both bullying and dating aggression. We consider bullying from a developmental-contextual perspective and consider risk factors associated with the typical developmental patterns for bullying and dating aggression, including developmental and sociodemographic, individual attributes, and family, peer group, community, and societal relationship contexts that might lead some children and youths to follow developmental pathways that lead to bullying and dating aggression. We conclude by discussing implications for intervention with a review of evidence-based interventions.

    Testing of the technical feasibility of radurization of fresh dates was attempted. In addition preliminary studies were carried out to investigate the applicability of gamma rays to date syrup manufacture. The varieties Zahdi, Lelwi and Tabarzel were studied at different stages of ripening. The eating quality of fresh dates was not affected significantly by irradiation even with doses of 270 and 540 krad. The duration of the softening process, after-ripening, of dates was prolonged by low doses of 10-30 krad in the majority of the experimental batches. The time period of after-ripening was reduced with 270 krad, as well as with 540 krad as a result of shortening of the induction period, i.e. the time after which the date begins to soften. The microbial spoilage of khalaal Lelwi dates was considerably reduced by irradiation with doses above 90 krad. The dibis yield of fully rutab dates was highly increased by the radiation doses of 375 to 2000 krad. The darkness and viable cell count of dibis pressed from irradiated dates were significantly lower than that of untreated dates. (F.J.)

    Adolescent dating violence is increasingly recognized as a public health problem. Our qualitative investigation sought input from urban, African-American adolescents at risk for dating violence concerning (Tjaden and Thoennes in Full report of the prevelance, incidence, and consequences of violence against women: findings from the national violence against women survey. US Department of Justice, Washington, DC, 2000) dating violence descriptions, (WHO multi-country study on women's health and domestic violence against women: Summary report of initial results on prevalence, health outcomes and women's responses. World Health Organization, Geneva, 2005) preferences for help-seeking for dating violence, and (Intimate partner violence in the United States. Bureau of Justice Statistics, US Department of Justice, Office of Justice Programs, Washington, DC, 2007) recommendations for a teen dating violence resource center. Four focus groups were conducted with urban, African American adolescents (n = 32) aged 13-24 recruited from an urban adolescent clinic's community outreach partners. Qualitative analysis was conducted. Participants assigned a wide range of meanings for the term "relationship drama", and used dating violence using language not typically heard among adults, e.g., "disrespect". Participants described preferences for turning to family or friends before seeking formal services for dating violence, but reported barriers to their ability to rely on these informal sources. When asked to consider formal services, they described their preferred resource center as confidential and safe, with empathetic, non-judgmental staff. Teens also gave insight into preferred ways to outreach and publicize dating violence resources. Findings inform recommendations for youth-specific tailoring of violence screening and intervention efforts. Current evidence that slang terms, i.e., "drama", lack specificity suggests that they should not be integrated within screening protocols

    The two-decade long history of thermoluminescene as a pottery dating method is surveyed with particular reference to the various problems that have been encountered in the Oxford Laboratory's research programme. Effects, such as supralinearity and radon emanation, are explained in terms of how they are measured and how their existence influences thermoluminescence (TL) dating accuracy (currently close to plus minus 7% per analysis). Illustrations of Thermoluminescence (TL) applications include a Nok culture terracotta from Nigeria and a Cambodia bronze Buddha figure of the Khmer period, dated ising the ceramic-like casting-core retained within it.

    In public health, the generation, management, and transfer of knowledge all need major improvement. Problems in generating knowledge include an imbalance in research funding, publication bias, unnecessary studies, adherence to fashion, and undue interest in novel and immediate issues. Impaired generation of knowledge, combined with a dated and inadequate process for managing knowledge and an inefficient system for transferring knowledge, mean a distorted body of evidence available for decisionmaking in public health. This article hopes to stimulate discussion by proposing a Global Registry of Anticipated Public Health Studies. This prospective, comprehensive system for tracking research in public health could help enhance collaboration and improve efficiency. Practical problems must be discussed before such a vision can be further developed. PMID:17413073

    Despite theoretical and empirical evidence suggesting that the family environment plays a central role in Latino youth development, relatively little is known about how family processes influence dating violence victimization among Latino adolescents. To address this gap in the literature, we used data from 210 Latino parents and their 13- to 15-year-old adolescents to examine associations between several different family processes, including both parenting practices (parent monitoring, parent-adolescent communication) and aspects of the family relational climate (family cohesion, family conflict, acculturation conflict) and psychological, physical, and sexual dating violence victimization. Consistent with expectations, lower levels of family cohesion and higher levels of family and acculturation conflict were associated with risk for dating violence victimization, although associations varied depending on victimization type. In contrast, neither parental monitoring nor parent-adolescent communication was significantly associated with any type of dating violence victimization. In addition, we found that parent, but not teen, Anglo-American acculturation was associated with higher dating violence victimization risk. Findings suggest that family-based dating abuse prevention programs for Latino youth should seek to increase family cohesion and decrease family conflict, including acculturation-based conflict.

  9. A Primer for Preventing Teen Dating Violence? The Representation of Teen Dating Violence in Young Adult Literature and Its Implications for Prevention.

    Storer, Heather L; Strohl, Katyayani R

    2016-09-18

    Teen dating violence (TDV) is a significant public health issue. Preventing TDV requires attention to risk and protective factors across ecological system levels. The media is one of the primary cultural drivers of societal-level social scripts about the causes of TDV. Framing theory asserts that the media's portrayal of social issues, including what contextual information is included and/or excluded, affects individual-level attitudes about TDV and potential policy responses. This study investigates the representation of TDV in young adult (YA) literature, a media genre that is marketed to adolescent audiences. Data include all YA novels (N = 8) that have a primary focus on TDV. Texts were analyzed systematically using thematic content analysis methods. Results indicate that the antecedents of TDV were portrayed as being related to victim personal characteristics such as inexperience in relationships and low self-esteem. Rather than underscoring how societal-level factors contribute to TDV, perpetration was seen as stemming from family dysfunction and mental health issues. These results underscore how the structural determinants of TDV have been overshadowed in the media's portrayal of TDV, in favor of narrow portrayals of victimization and perpetration. Implications for TDV prevention programs including the importance of media literacy are discussed. © The Author(s) 2016.

    The StarDate Black Hole Encyclopedia website was developed over the past seven years to provide an extensive but easy-to-read resource for the public and students. A Spanish-language version, Enciclopedia de agujeros negros, is also available at blackholes.radiouniverso.org. Evaluation shows that the sites are used by the public, students, and astronomy professionals, and the site is among the top references in most web searches for individual black holes. The site comprises seven major subsections: Basics, Directory, Research, History, Pop Culture, News, and Resources. The Basics section introduces black holes, explains how they are discovered and studied, and covers their basis in the theory of gravity. This section also includes a six-minute video introduction, “Black Holes: Stranger than Fiction.” The Directory section contains extensive descriptions of more than 80 well-known stellar, intermediate, and supermassive black holes as well as images and vital statistics of each. The Research section takes a look at three NSF-funded projects, including the work of Andrea Ghez, Karl Gebhardt and Jenny Greene, and the LIGO project. The History section provides a timeline of black holes from Isaac Newton to the present. Some of the best and worst roles played by black holes in films, TV shows, and books are included in the Pop Culture section (and pop culture references and images are sprinkled through the rest of the site). An archive of news reports about black holes is available in the News section, which provides links to the original stories or press releases. And the Resources section offers FAQs, articles from StarDate magazine and radio programs, activities for students that are tied to national standards, a glossary, and a reading list of books and websites. We have conducted both quantitative and qualitative evaluation on the black hole websites. This material is based upon work supported by the National Science Foundation under Grant No. 0935841. Any

    In the Savannah River Site's (SRS') Solid Waste Management Program, a key to success is the Public Involvement Program. The Solid Waste Division at SRS manages the site's transuranic, low-level, mixed, and hazardous wastes. All decisions associated with management of this waste are of interest to the public and successful program implementation would be impossible without a vigorous public involvement program. The SRS Solid Waste Division (SWD) and its Department of Energy (DOE) customer developed, implemented, and maintain a comprehensive public participation and communications program. It is staffed by public participation and technical specialists to ensure information is presented in a manner that is technically accurate while being tailored for understanding by people without a technical background. The program provides the public with accurate, complete, timely information and early meaningful participation opportunities. It also fulfills the public participation activities required by laws, regulations, DOE Orders, and negotiated agreements. The primary goal of the SWD Public Participation Program is to fulfill the objectives of the SWD and SRS Strategic Plans to ''build trust and communicate openly, honestly, and responsibly with employees, customers, stakeholders, and regulators,'' and to ''work to extend the support of external stakeholders for the pursuit of SRS and DOE Complex business goals.'' This paper focuses on the public participation program goals, the implementation through formal plans and objectives, targeted waste management programs and specific audiences, and specific effects of the program on waste management activities. A discussion of the DOE and contractor teaming along with how plans are carried out is also included

    2017-07-27

    Cyber culture with its related e-commerce, expanded since the 2000s through the advent of social network platforms, incites participants to engage in hyper-exposure and spectacularization of their private lives, with inherent consequences for personal image and privacy, publicizing private matters (especially those pertaining to sexuality and corporality) in the digital media. This raises the need to understand how the phenomenon of cyber dating abuse in affective and sexual relationships is conceptualized and characterized in scientific studies, which health problems are associated with it, and which social technologies are suggested for intervention. This form of abuse is a new expression of intimate partner violence that involves, among other practices, posting embarrassing photos and videos and intimate messages without prior consent, with the purpose of humiliating and defaming the person. The current study is an integrative systematic review, including 35 articles, with a predominance of studies in the United States (22). Types of cyber dating abuse range from direct aggression to stalking. Despite the high prevalence, especially among adolescents and youth, the literature highlights that this type of cyber abuse is often taken for granted. The suggested interventions are mostly for prevention and awareness-raising concerning relationship abuse, action by school counselors, and family orientation. The high reciprocity of cyber dating abuse between males and females indicates that future studies should attempt to elucidate how the dynamics of gender violence are reproduced or subverted by it.

  15. Understanding the hesitancy to disclose teen dating violence: Correlates of self-efficacy to deal with teen dating violence

    Full Text Available Dating violence (DV is now recognized as an important public health issue. Prevention and intervention programs are being implemented in school contexts. Such initiatives aim to raise awareness among potential victims and offenders as well as among peer bystanders and offer adequate interventions following disclosure. Yet, a major challenge remains as teenagers may not disclose their victimization or may not feel self-efficient to deal with DV if they witness such violence. As such, teen DV remains largely hidden. A representative sample of 8194 students (age 14-18 in the province of Quebec, Canada was used to explore teenagers’ self-efficacy to reach out for help or to help others in a situation of DV victimization and perpetration. Analyses are conducted to identify possible correlates of self-efficacy in terms of socio-demographic variable (sex, age and a history of child sexual abuse and dating victimization. Implications for preven­tion and support strategies are discussed.

    Dating violence is a major public health issue among youth. Overweight/obese adolescents experience peer victimization and discrimination and may be at increased risk of dating violence victimization. Furthermore, given the stigma associated with overweight/obesity, perceptions and misperceptions of overweight may be more important than actual weight status for dating violence victimization. This study examines the association of three weight indices (weight status, perceived weight, and weight perception accuracy) with psychological and physical dating violence victimization. The 2010 baseline survey of the 7-year NEXT Generation Health Study used a three-stage stratified clustered sampling design to select a nationally representative sample of U.S. 10th-grade students (n = 1,983). Participants who have had a boyfriend/girlfriend reported dating violence victimization and perceived weight. Weight status was computed from measured height/weight. Weight perception accuracy (accurate/underestimate/overestimate) was calculated by comparing weight status and perceived weight. Gender-stratified regressions examined the association of weight indices and dating violence victimization. Racial/ethnic differences were also examined. The association of weight indices with dating violence victimization significantly differed by gender. Overall, among boys, no associations were observed. Among girls, weight status was not associated with dating violence victimization, nor with number of dating violence victimization acts; however, perceived weight and weight perception accuracy were significantly associated with dating violence victimization, type of victimization, and number of victimization acts. Post hoc analyses revealed significant racial/ethnic differences. White girls who perceive themselves (accurately or not) to be overweight, and Hispanic girls who are overweight, may be at increased risk of dating violence victimization. These findings suggest a targeted approach to

    2015-10-01

    The relationship between reported bullying, reported dating violence, and dating relationship quality measured through couple observations was examined. Given past research demonstrating similarity between peer and dating contexts, we expected that bullying would predict negative dating experiences. Participants with dating experience (n = 585; 238 males, M(age) = 15.06) completed self-report assessments of bullying and dating violence perpetration and victimization. One month later, 44 opposite-sex dyads (M(age) = 15.19) participated in behavioral observations. In 10-min sessions, couples were asked to rank and discuss areas of relationship conflict while being video-recorded. Qualities of the relationship were later coded by trained observers. Regression analysis revealed that bullying positively predicted dating violence perpetration and victimization. Self-reported bullying also predicted observations of lower relationship support and higher withdrawal. Age and gender interactions further qualified these findings. The bullying of boys, but not girls, was significantly related to dating violence perpetration. Age interactions showed that bullying was positively predictive of dating violence perpetration and victimization for older, but not younger adolescents. Positive affect was also negatively predicted by bullying, but only for girls. These findings add to the growing body of evidence that adolescents carry forward strategies learned in the peer context to their dating relationships. © The Author(s) 2014.

    Teen dating violence and sexual violence are severe public health problems. Abusive behaviors within the context of dating or romantic relationships are associated with adverse health outcomes. Promoting positive bystander intervention and increasing knowledge of abusive behaviors are promising strategies for preventing dating and sexual violence. Coaching Boys Into Men (CBIM) is an evidence-based, athletic coach-delivered dating violence prevention program that has been shown to increase positive bystander behaviors and reduce abuse perpetration among high school male athletes. Identifying specific barriers and facilitators based on the coaches' experiences with program delivery combined with the coaches' and athletes' program perceptions may help optimize future CBIM implementation and sustainability. Semi-structured interviews with coaches (n = 36) explored the implementers' perspectives on strategies that worked well and potential barriers to program implementation. Ten focus groups with male athletes (n = 39) assessed their experiences with CBIM and the suitability of having their coaches deliver this program. Coaches described using the CBIM training cards and integrating program delivery during practice. Athletes reported coaches routinely delivering the CBIM program and adding their own personal stories or examples to the discussions. Key facilitators to program implementation include support from the violence prevention advocate, the ease of integrating CBIM into the sports season, and using the program materials. Barriers to implementation included finding sufficient time for the program, dynamics of delivering sensitive program content, and participant constraints. Coaches and athletes alike found the program feasible and acceptable to implement within the sports setting. Both coaches and athletes offered insights on the implementation and the feasibility and acceptability of CBIM within school-based athletic programs. These experiences by

  5. The unexpected truth about dates and hypoglycemia

    2016-01-01

    Full Text Available Background: Dates are a concentrated source of essential nutrients, vitamins, minerals, and carbohydrates (CHOs, which are necessary for the maintenance of optimum health. Most of the CHOs in dates come from sugars including glucose and fructose. Dates are commonly consumed in Saudi Arabia, particularly at the time of breaking the fast to provide instant energy and maintain blood sugar level. However, dates may cause hypoglycemia in a rare condition named as heredity fructose intolerance (HFI, and a few families have been to see us with a history of that nature. This is to report the preliminary results of an on-going study of a group of patients who get symptoms of hypoglycemia following the ingestion of dates and have suffered for years without an accurate diagnosis. Methodology: This report is based on three patients, from the same family, living in a date growing region of the Kingdom of Saudi Arabia (KSA. The patients had been to several medical centers without getting any definite answers or diagnosis until they were referred to the Gastroenterology Clinic of King Fahd Hospital of the University, Al-Khobar, KSA. The data were obtained by careful history and laboratory investigations, and a final diagnosis of HFI made on fructose intolerance test (FIT. Results: The patients reported that they had avoided eating dates because of various symptoms, such as bloating, nausea, and even hypoglycemia when larger amounts were consumed. Their other symptoms included sleepiness, sweating, and shivering. After full examinations and necessary laboratory tests based on the above symptoms, FIT was performed and the patients were diagnosed with HFI. They were referred to a dietitian who advised a fructose-free diet. They felt well and were free of symptoms. Conclusion: HFI may remain undiagnosed until adulthood and may lead to disastrous complications and even death. The diagnosis can only be suspected after a careful dietary history is taken supported by

    To understand the positives and negatives of online dating according to the lived experience of older women, telephone interviews were conducted with 45 women ages 50+ who date online. Interviews were audio recorded, transcribed verbatim, and thematically team coded. The opportunity to expand one's social network for both friendships and romantic partners, the ability to control dating risks and pace of relationship formation, and knowing more about one's partner were significant reported benefits of online dating. Dating online also includes unique risks, such as pervasive lying, attempted financial exploitation in the form of scammers, and unwanted electronic sexual aggression.

    People with disabilities are largely absent from mainstream health research. Exclusion of people with disabilities may be explicit, attributable to poorly justified exclusion criteria, or implicit, attributable to inaccessible study documents, interventions, or research measures. Meanwhile, people with disabilities experience poorer health, greater incidence of chronic conditions, and higher health care expenditure than people without disabilities. We outline our approach to "accessible research design"-research accessible to and inclusive of people with disabilities. We describe a model that includes 3 tiers: universal design, accommodations, and modifications. Through our work on several large-scale research studies, we provide pragmatic examples of accessible research design. Making efforts to include people with disabilities in public health, epidemiological, and outcomes studies will enhance the interpretability of findings for a significant patient population.

    Full Text Available The topic of this issue is PUBLIC SPACES. It is familiar and clear to every citizen. The streets and courtyards as childhood experiences remain with us forever. And these are the places where we come with our parents at weekends, where we meet friends, where we have dates and where we already come for a walk with our children.The history of public spaces is long and captivating. It was the main city squares where the most important events took place in history. The Agoras of Ancient Greece and the Roman Forums, the squares of Vatican, Paris and London, Moscow and Saint Petersburg… Greve, Trafalgar, Senate, Palace, Red, Bolotnaya – behind every name there is life of capitals, countries and nations.Public spaces, their shapes, image and development greatly influence the perception of the city as a whole. Both visitors and inhabitants can see in public spaces not only the visage but the heart, the soul and the mind of the city.Unfortunately, sometimes we have to prove the value of public spaces and defend them from those who consider them nothing but a blank space, nobody’s land destined for barbarous development.What should happen to make citizens perceive public spaces as their own and to make authorities consider development and maintenance of squares and parks their priority task against the  background of increasing competition between cities and the fight for human capital? Lately they more often say about “a high-quality human capital”. And now, when they say “the city should be liveable” they add “for all groups of citizens, including the creative class”.

    The paper will comment on a few issues of particular relevance to Australasia. Thermoluminescent (TL) methods applied to open sites have been demonstrated to be effective. A particularly good example of this is to be found in the South East of South Australia, where a sequence of low ranges runs roughly parallel with the coast. They represent relict sand dunes left behind, on a slowly rising land surface by successive interglacial incursions of the sea at roughly 120 ka intervals. Comparison with ages established on independent geological grounds allows a test of quartz TL and IRSL ages that is believable back to 500 ka. Older than this, we do not yet understand the physics of the quartz well enough to go unequivocally forward (backward?). Similar results are emerging elsewhere. With dating limits being pushed ever further back, the time variation of the environmental radiation giving rise to the stored luminescent energy needs to be addressed. Particularly at wet sites, radioactive disequilibrium must be considered. In any case, a time profile of the radiation dose rate needs to be determined.In dating a given site or sites the value of ages obtained by any dating method,including C-14, is enhanced by parallel measurements with an different method

  9. U-Th Burial Dates on Ostrich Eggshell

    Science.gov (United States)

    Sharp, W. D.; Fylstra, N. D.; Tryon, C. A.; Faith, J. T.; Peppe, D. J.

    2015-12-01

    Obtaining precise and accurate dates at archaeological sites beyond the range of radiocarbon dating is challenging but essential for understanding human origins. Eggshells of ratites (large flightless birds including ostrich, emu and others) are common in many archaeological sequences in Africa, Australia and elsewhere. Ancient eggshells are geochemically suitable for the U-Th technique (1), which has about ten times the range of radiocarbon dating (>500 rather than 50 ka), making eggshells attractive dating targets. Moreover, C and N isotopic studies of eggshell provide insights into paleovegetation and paleoprecipitation central to assessing past human-environment interactions (2,3). But until now, U-Th dates on ratite eggshell have not accounted for the secondary origin of essentially all of their U. We report a novel approach to U-Th dating of eggshell that explicitly accounts for secondary U uptake that begins with burial. Using ostrich eggshell (OES) from Pleistocene-Holocene east African sites, we have measured U and 232Th concentration profiles across OES by laser ablation ICP-MS. U commonly peaks at 10s to 100s of ppb and varies 10-fold or more across the ~2 mm thickness of OES, with gradients modulated by the layered structure of the eggshell. Common Th is high near the shell surfaces, but low in the middle "pallisade" layer of OES, making it optimal for U-Th dating. We determine U-Th ages along the U concentration gradient by solution ICP-MS analyses of two or more fractions of the pallisade layer. We then estimate OES burial dates using a simple model for diffusive uptake of uranium. Comparing such "U-Th burial dates" with radiocarbon dates for OES calcite from the same shells, we find good agreement in 7 out of 9 cases, consistent with rapid burial and confirming the accuracy of the approach. The remaining 2 eggshells have anomalous patterns of apparent ages that reveal they are unsuitable for U-Th dating, thereby providing reliability criteria innate

  10. Development of BASIC program for radiocarbon dating

    International Nuclear Information System (INIS)

    Omoto, Kunio

    1982-01-01

    The continuous improvement of the system and the needs have produced the successful radiocarbon dating system of today to detect very low energy β-radioactivity. However, it still takes longer than 1,000 minutes for a sample counting. In a gas counting system, it is very difficult to keep the drift of impressed high voltage for a proportional counter less than 5 volts throughout the counting time. The temperature and the characteristics of gas itself also change during experiment. The accumulation of the above drift and errors are closely concerned with the accuracy and reliability of the radiocarbon date. The detection and reduction of the errors are only possible by using a ''fully automatic radiocarbon dating system'' linked to a personal computer system. In this paper, the author presents the BASIC (Beginners All-purpose Symbolic Instruction Code) program for a fully automatic radiocarbon dating system. In this paper, the outline of the system and software development are described. The details of the program include the description for gas-collection, gas-enclosing, plateau counting, β-ray counting, age calculation and data file maintenance. The author wrote numerous remark statements into the program so that it can be understood by users without detailed knowledge of the operation of a personal computer system or of the radiocarbon dating. Using this system, the author found that the radiocarbon dating has greatly progressed in speed and labour-saving, and that the accuracy and reliability of the date itself has also improved much than former manual systems.

    Leck, Kira

    2006-10-01

    Researchers have associated minimal dating with numerous factors. The present author tested shyness, introversion, physical attractiveness, performance evaluation, anxiety, social skill, social self-esteem, and loneliness to determine the nature of their relationships with 2 measures of self-reported minimal dating in a sample of 175 college students. For women, shyness, introversion, physical attractiveness, self-rated anxiety, social self-esteem, and loneliness correlated with 1 or both measures of minimal dating. For men, physical attractiveness, observer-rated social skill, social self-esteem, and loneliness correlated with 1 or both measures of minimal dating. The patterns of relationships were not identical for the 2 indicators of minimal dating, indicating the possibility that minimal dating is not a single construct as researchers previously believed. The present author discussed implications and suggestions for future researchers.

  16. The Impact of Including Immigrants without Permanent Residence Status in the Public Health Insurance System in the Czech Republic

    Directory of Open Access Journals (Sweden)

    Tepperová Jana

    2016-03-01

    Full Text Available Whether an individual can or cannot participate in the Czech public health insurance system depends on several characteristics, one of which is whether he/she has permanent residence status in the Czech Republic, and a second whether he/she is employed. This means that those without permanent residence status, including self-employed migrants from third countries, their dependent relatives, and the dependent relatives of third country employees in the Czech Republic, cannot participate in the public health insurance system. Some argue that such migrants should be included in the system, since commercial health insurance is disadvantageous and the contributions they would pay into the public health insurance system would increase the public health insurance agencies’ income. We estimate the value of the contributions to public health insurance that would be paid by third country self-employed and non-working immigrants, if they were insured based on data from 2011 to 2013, and compare this to the assumed costs of their medical care. To calculate the contributions for self-employed migrants we use data on the distribution of the tax base for self-employed persons from personal income tax returns. Our estimation results in an overall negative balance of 22 million CZK on the data for 2012 and 2013. In the current system this deficit would be covered by the state, which would pay contributions to the system for certain (state insured persons amounting to 97 million CZK; overall therefore the inclusion of these immigrants would result in a positive balance of 75 million CZK.

  17. Radiometric dating methods

    International Nuclear Information System (INIS)

    Bourdon, B.

    2003-01-01

    The general principle of isotope dating methods is based on the presence of radioactive isotopes in the geologic or archaeological object to be dated. The decay with time of these isotopes is used to determine the 'zero' time corresponding to the event to be dated. This paper recalls the general principle of isotope dating methods (bases, analytical methods, validation of results and uncertainties) and presents the methods based on natural radioactivity (Rb-Sr, Sm-Nd, U-Pb, Re-Os, K-Ar (Ar-Ar), U-Th-Ra- 210 Pb, U-Pa, 14 C, 36 Cl, 10 Be) and the methods based on artificial radioactivity with their applications. Finally, the methods based on irradiation damages (thermoluminescence, fission tracks, electron spin resonance) are briefly evoked. (J.S.)

    Objective To determine prevalence and correlates of dating violence, dating victimization, and dating aggression among males and females age 14–20 seeking emergency department (ED) care. Methods Systematic sampling of subjects age 14–20 seeking care at a single large academic ED between 9/2010- 3/2013. Participants completed a computerized, self-administered, cross-sectional survey of demographics, dating violence from physical abuse measures of the Conflict in Adolescent Dating Relationships Inventory, associated behaviors, and ED health service use. Separate analyses were conducted for males and females. Results 4389 youth (86.1% participation rate) were screened, and 4089 (mean age 17.5 years, 58% female) were eligible for analysis. Almost 1 in 5 females (n= 215, 18.4%) and 1 in 8 males (n= 212, 12.5%) reported past year dating violence. Of females, 10.6% reported dating victimization, and 14.6% dating aggression, while of males, 11.7% reported dating victimization, and 4.9% reported dating aggression. Multivariate analyses showed variables associated with any male dating violence were African American race (AOR 2.26, CI 1.54–3.32), alcohol misuse (AOR 1.03, CI 1.00–1.06), illicit drug misuse (AOR 2.38, CI 1.68–3.38), and depression (AOR 2.13, CI 1.46–3.10); any female dating violence was associated with African-American race (AOR 1.68, CI 1.25–2.25), public assistance (AOR 1.64, CI 1.28–2.09), grades D and below (AOR 1.62, CI 1.07–2.43), alcohol misuse (AOR 1.04, CI 1.02–1.07), illicit drug misuse (AOR 2.85, CI 2.22–3.66), depression (AOR 1.86, CI 1.42–2.44), and any past year ED visit for intentional injury (AOR 2.64, CI 1.30–5.40). Conclusions Nearly 1 of 6 male and female adolescents seeking ED care report recent dating violence, and health disparities remain among this population. Dating violence was strongly associated with alcohol, illicit drug misuse, and depression, and correlated with prior ED service utilization among female

  1. Narratives of Compensated Dating of Girls in Hong Kong Using Routine Activity Theory: Results of a Focus Group Study of Guardians.

    2018-02-01

    This article presents public discourses on compensated dating of adolescent girls in Chinese society. Data are obtained from eight focus groups comprising 50 guardians at private, parochial, and public levels (i.e., social workers, police officers, parents of students, and community representatives). Qualitative data are used to demonstrate how the guardians conceptualize and contextualize compensated dating as an outcome of the dynamics of societal features. Social features such as contemporary ideologies, Internet technology advancement, commercialization of human relationships, and ambiguity between "right" and "wrong" motivate the service providers and customers of compensated dating, and accelerate their convergence and weakened levels of guardianship in society. This study is the first to connect the features of compensated dating of adolescent girls with recent societal changes using the routine activity approach. The findings confirm the application of the routine activity approach in the phenomenon of girls' compensated dating, and also offer theoretical and practical implications.

  2. Interactive publications: creation and usage

    Thoma, George R.; Ford, Glenn; Chung, Michael; Vasudevan, Kirankumar; Antani, Sameer

    2006-02-01

    As envisioned here, an "interactive publication" has similarities to multimedia documents that have been in existence for a decade or more, but possesses specific differentiating characteristics. In common usage, the latter refers to online entities that, in addition to text, consist of files of images and video clips residing separately in databases, rarely providing immediate context to the document text. While an interactive publication has many media objects as does the "traditional" multimedia document, it is a self-contained document, either as a single file with media files embedded within it, or as a "folder" containing tightly linked media files. The main characteristic that differentiates an interactive publication from a traditional multimedia document is that the reader would be able to reuse the media content for analysis and presentation, and to check the underlying data and possibly derive alternative conclusions leading, for example, to more in-depth peer reviews. We have created prototype publications containing paginated text and several media types encountered in the biomedical literature: 3D animations of anatomic structures; graphs, charts and tabular data; cell development images (video sequences); and clinical images such as CT, MRI and ultrasound in the DICOM format. This paper presents developments to date including: a tool to convert static tables or graphs into interactive entities, authoring procedures followed to create prototypes, and advantages and drawbacks of each of these platforms. It also outlines future work including meeting the challenge of network distribution for these large files.

    2015-03-01

    Dating violence is commonly perpetrated in adolescence, making it imperative to understand risk factors in order to inform prevention efforts. Although individual norms supporting dating violence are strongly related to its perpetration, few studies have examined their longitudinal impact. Moreover, the influence of class norms (i.e., norms for students in the same grade, cohort, and school) supporting dating violence on perpetration has rarely been studied. The current study examined longitudinal relationships between individual and class norms supporting dating violence and perpetration of physical and psychological dating violence. Participants were two cohorts of sixth graders from 37 schools who were in dating relationships at Wave 1 and 6 months later at Wave 2 (N = 2,022; 43% female; 52% African American, 21% Latino/a, 20% White, and 7% other). The analyses used a multilevel approach, with students represented at Level 1 and classes (n = 74) at Level 2. The models tested direct effects of Wave 1 individual and class norms supporting dating violence on subsequent changes in perpetration of dating violence at Wave 2 and the extent to which gender moderated these relationships. The findings indicated that greater individual norms supporting male dating violence predicted greater change in perpetration of physical and psychological dating violence and greater individual norms supporting female dating violence predicted greater change in perpetration of psychological dating violence. Greater class norms supporting male dating violence predicted greater change in perpetration of physical dating violence; whereas greater class norms supporting female dating violence predicted less change in perpetration of physical dating violence. These findings highlight the need to address norms in early adolescence.

  12. Up-Dating: Ratings of Perceived Dating Success Are Better Online than Offline.

    Science.gov (United States)

    Fullwood, Chris; Attrill-Smith, Alison

    2018-01-01

    The primary aims of this study were to test whether perceived dating success would differ between offline and online zero-acquaintance dating contexts and to investigate the role that self-esteem might play in these evaluations. Participants were presented with the same photos of targets in either an offline or online dating scenario and rated their chances of dating success along with their perceptions of how attractive they thought the target would consider them. Higher self-esteem individuals believed they would be rated as more attractive. There was an overall perception that, irrespective of self-esteem level, meeting online would lead to better chances of dating success. These findings are considered in relation to an increased ability to more precisely manage impressions and develop an image of the self which would be evaluated more positively online.

    Tussey, Brian Ermon; Tyler, Kimberly A; Simons, Leslie Gordon

    2018-02-01

    Although dating violence is prevalent among college students, little is known about how both attachment style and participation in risky behaviors contribute to this pattern of violence. To address this literature gap, we examine the role of poor parenting, child abuse, attachment style, and risky sexual and drug use behaviors on dating violence perpetration among 1,432 college students (51% female). Path analysis results revealed that females were more likely to report greater attachment anxiety but lower attachment avoidance compared with males. Correlates of attachment anxiety included child physical abuse, witnessing parental violence, and poorer maternal relationship quality whereas attachment avoidant behavior was linked to more physical abuse and poorer maternal relationship quality. Females were more likely to perpetrate dating violence as were those with greater attachment anxiety and lower attachment avoidance. Other correlates of dating violence perpetration included sexual and drug risk behaviors. Finally, distal factors (i.e., more child physical abuse and poorer maternal relationship quality) also were associated with dating violence perpetration. Study implications are also discussed.

    Objective To examine dating violence perpetration and victimization (physical, psychological, and sexual) and lifetime substance use (alcohol, marijuana, and hard drugs) as longitudinal predictors of adolescents’ risky sexual behavior across one year, and to determine whether predictors varied across adolescents’ gender and ethnicity. Methods A sample of Caucasian, African American, and Hispanic male and female adolescents from 7 public high schools in Texas (N = 882) participated. Adolescents completed self-report measures of dating violence, lifetime substance use, and risky sexual behavior at baseline and, 1-year later, completed a second assessment of their risky sexual behavior. Results Path analysis demonstrated that greater physical dating violence victimization, lifetime alcohol use, lifetime marijuana use, and age (being older) were all significant predictors of risky sexual behavior at the 1-year follow-up. These results did not vary across gender or the three ethnic groups (Caucasian, African American, and Hispanic). Conclusions Overall, substance use was a longitudinal predictor of risky sexual behavior across the three ethnic groups, with physical dating violence victimization being the only type of dating violence longitudinally predicting risky sexual behavior. Prevention efforts should consider the roles of physical dating violence and substance use in preventing risky sexual behavior. PMID:25797949

    Violence in dating relationships involves dimensions such as physical, psychological and sexual abuse, requiring strategies for prevention and early intervention. To identify the socio-demographic variables that influence violence in dating relationships; to identify whether having been a victim and/or witnessing violence in childhood has significant effect on violence in dating relationships; to verify the correlation between violence in dating relationships and psychological well-being. Quantitative non-experimental, cross-sectional, descriptive correlational study. Data collection conducted by a socio-demographic characterisation questionnaire; Dating Relationship Victimization Practices and Behaviours Scale and Demonstration of Psychological Well-Being Measurement Scale. The non-probabilistic, convenience sample consisted of 203 students from the Health School of Viseu. Mostly female students gender; Mean age of 18.85 years, minimum of 18 and maximum of 34; Gender and having been a victim or witness of violence against children and sexual violence are variables that seem to intervene in dating violence and psychological well-being. Age has an influence on psychological well-being. Stalking violence and psychological violence were more prevalent in the study sample. It was found that the presence of any type of violence is associated with a decrease in student psychological well-being. By analysing the results we can infer the need to include this topic in education/training, active methodologies and effective participation of all stakeholders in the process, with a view to promoting and developing relationship and affective skills.

    We determine prevalence and correlates of dating violence, dating victimization, and dating aggression among male and female patients aged 14 to 20 years seeking emergency department (ED) care. This was a systematic sampling of subjects aged 14 to 20 years seeking care at a single large academic ED between September 2010 and March 2013. Participants completed a computerized, self-administered, cross-sectional survey of demographics, dating violence from physical abuse measures of the Conflict in Adolescent Dating Relationships Inventory, associated behaviors, and ED health service use. Separate analyses were conducted for male and female patients. Four thousand three hundred eighty-nine youths (86.1% participation rate) were screened, and 4,089 (mean age 17.5 years; 58% female patients) were eligible for analysis. Almost 1 in 5 female patients (n=215; 18.4%) and 1 in 8 male patients (n=212; 12.5%) reported past-year dating violence. Of female patients, 10.6% reported dating victimization and 14.6% dating aggression, whereas of male patients, 11.7% reported dating victimization and 4.9% reported dating aggression. Multivariate analyses showed that variables associated with any male dating violence were black race (adjusted odds ratio [AOR] 2.26; 95% CI 1.54 to 3.32), alcohol misuse (AOR 1.03; 95% CI 1.00 to 1.06), illicit drug use (AOR 2.38; 95% CI 1.68 to 3.38), and depression (AOR 2.13; 95% CI 1.46 to 3.10); any female dating violence was associated with black race (AOR 1.68; 95% CI 1.25 to 2.25), public assistance (AOR 1.64; 95% CI 1.28 to 2.09), grades D and below (AOR 1.62; 95% CI 1.07 to 2.43), alcohol misuse (AOR 1.04; 95% CI 1.02 to 1.07), illicit drug use (AOR 2.85; 95% CI 2.22 to 3.66), depression (AOR 1.86; 95% CI 1.42 to 2.44), and any past year ED visit for intentional injury (AOR 2.64; 95% CI 1.30 to 5.40). Nearly 1 of 6 male and female patients aged 14 to 20 years and seeking ED care report recent dating violence, and health disparities remain among

  7. Internet dating as a project: the commodification and rationalisation of online dating

    Directory of Open Access Journals (Sweden)

    2015-04-01

    Full Text Available Based on qualitative empirical data from two studies on Internet dating in Slovenia, this paper discusses the social contexts of the Internet dating of heterosexual men and women and homosexual men. Special attention is given to different aspects of the commodification and rationalisation of dating in the process of forming potential (romantic partnerships. First, we discuss our respondents’ reasons for using the Internet to get in touch with potential (romantic partners. Second, we focus on the demands and strategies of targeted market- ing in personal profile writing and, finally, on the process of selecting potential partners. Our study shows that the primary understanding of Internet dating among people who engage in it is its economic nature. Together with targeted marketing and the predeter- mined criteria for choosing interesting others, Internet dating can thus be understood as a market that encourages rationalisation and commodification in the process of forming intimate relationships.

    Cover crop benefits include nitrogen accumulation and retention, weed suppression, organic matter maintenance, and reduced erosion. Organic farmers need region-specific information on winter cover crop performance to effectively integrate cover crops into their crop rotations. Our research objective was to compare cover crop seeding mixtures, planting dates, and termination dates on performance of rye (Secale cereale L.) and hairy vetch (Vicia villosa Roth) monocultures and mixtures in the maritime Pacific Northwest USA. The study included four seed mixtures (100% hairy vetch, 25% rye-75% hairy vetch, 50% rye-50% hairy vetch, and 100% rye by seed weight), two planting dates, and two termination dates, using a split-split plot design with four replications over six years. Measurements included winter ground cover; stand composition; cover crop biomass, N concentration, and N uptake; and June soil NO3(-)-N. Rye planted in mid-September and terminated in late April averaged 5.1 Mg ha(-1) biomass, whereas mixtures averaged 4.1 Mg ha(-1) and hairy vetch 2.3 Mg ha(-1). Delaying planting by 2.5 weeks reduced average winter ground cover by 65%, biomass by 50%, and cover crop N accumulation by 40%. Similar reductions in biomass and N accumulation occurred for late March termination, compared with late April termination. Mixtures had less annual biomass variability than rye. Mixtures accumulated 103 kg ha(-1) N and had mean C:N ratio rye, 97 kg ha(-1) for the mixtures, and 119 kg ha(-1) for hairy vetch. Weeds comprised less of the mixtures biomass (20% weeds by weight at termination) compared with the monocultures (29%). Cover crop mixtures provided a balance between biomass accumulation and N concentration, more consistent biomass over the six-year study, and were more effective at reducing winter weeds compared with monocultures.

    1986-04-01

    Scientific methods of dating, born less than thirty years ago, have recently improved tremendously. First the dating principles will be given; then it will be explained how, through natural radioactivity, we can have access to the age of an event or an object; the case of radiocarbon will be especially emphasized. The principle of relative methods such as thermoluminescence or paleomagnetism will also be shortly given. What is the use for dating. The fields of its application are numerous; through these methods, relatively precise ages can be given to the major events which have been keys in the history of universe, life and man; thus, dating is a useful scientific tool in astrophysics, geology, biology, anthropology and archeology. Even if certain ages are still subject to controversies, we can say that these methods have confirmed evolution's continuity, be it on a cosmic, biologic or human scale, where ages are measured in billions, millions or thousands of years respectively.

    Das, N.R.

    2017-01-01

    Since the discovery of natural radioactivity in uranium, in the last decade of the nineteenth century, the nuclear property of radioactive decay of radionuclides at immutable rates has been effectively utilized in dating of varieties of naturally occurring geological matrices and the organisms which constantly replenish their "1"4C supply through respiration when alive on earth. During the period, applications of radiometric dating techniques have been extensively diversified and have enabled the geologists to indicate the absolute time scales of geological formations and the evolution of the solar system, the earth, meteorites, lunar rocks, etc. and the archaeologists to record the facts of history of several important events like dinosaur era, Iceman, the Shroud in Turin and many other ancient artefacts. In the development of dating methods, varieties of naturally occurring radio-isotopic systems with favorable half-lives ranging from about 10 years to over 100 billion years have been used as radiometric clocks.

  17. Luminescence dating in archaeology

    International Nuclear Information System (INIS)

    Wintle, A.G.

    2001-01-01

    Thermoluminescence (TL) dating is routinely applied to burnt lithic material. Simple fires are capable of enabling stones weighing a few hundred grams to reach 450 o C, thus zeroing the TL signal. TL dates have been obtained for Upper and Lower Paleolithic sites in Europe and the Near East. TL dating continues to be used for dating pottery and for authentification of ceramic works of art. Some recent studies report the use of optically stimulated luminescence (OSL) (also know as photoluminescence) for dating very small samples of quartz, e.g. from small pieces of pottery or frm metallurgical slag The major recent advance has been in the development of a reliable laboratory procedure for using the OSL signal from quartz to obtain the past radiation exposure. The quartz OSL signal is extremely sensitive to light and is reduced to a negligible level on exposure to direct sunlight for radionuclides during burial, signal to date san.sized quartz grains extracted from sediments, The OSL signal is stimulated by 470 nm light from emitting diodes and the detected using flirters centred on 340 nm A similar signal can be obtained from feldspar grain when are exposed to infrared wavelengths around 880 nm. The infrared stimulated luminescence (IRSL) signals is also rapidly depleted by exposure to sunlight, and dating of colluvial deposits from archaeological sites has been reported

  18. Gambling and the Health of the Public: Adopting a Public Health Perspective.

    Science.gov (United States)

    Korn, David A.; Shaffer, Howard J.

    1999-01-01

    During the last decade there has been an unprecedented expansion of legalized gambling throughout North America. Three primary forces appear to be motivating this growth: (1) the desire of governments to identify new sources of revenue without invoking new or higher taxes; (2) tourism entrepreneurs developing new destinations for entertainment and leisure; and (3) the rise of new technologies and forms of gambling (e.g., video lottery terminals, powerball mega-lotteries, and computer offshore gambling). Associated with this phenomenon, there has been an increase in the prevalence of problem and pathological gambling among the general adult population, as well as a sustained high level of gambling-related problems among youth. To date there has been little dialogue within the public health sector in particular, or among health care practitioners in general, about the potential health impact of gambling or gambling-related problems. This article encourages the adoption of a public health perspective towards gambling. More specifically, this discussion has four primary objectives:1. Create awareness among health professionals about gambling, its rapid expansion and its relationship with the health care system;2. Place gambling within a public health framework by examining it from several perspectives, including population health, human ecology and addictive behaviors;3. Outline the major public health issues about how gambling can affect individuals, families and communities;4. Propose an agenda for strengthening policy, prevention and treatment practices through greater public health involvement, using the framework of The Ottawa Charter for Health Promotion as a guide.By understanding gambling and its potential impacts on the public's health, policy makers and health practitioners can minimize gambling's negative impacts and appreciate its potential benefits.

  19. Updates on adolescent dating and sexual violence prevention and intervention.

    Science.gov (United States)

    Miller, Elizabeth; Jones, Kelley A; McCauley, Heather L

    2018-05-09

    Dating and sexual violence victimization are not uncommon in early adolescence and increase in prevalence throughout adolescence into young adulthood with profound health and social consequences. Greater attention to what works in prevention is needed to inform current policies and practices. Adolescent dating violence (ADV) and sexual violence victimization, including cyber dating abuse, are highly prevalent among adolescents. Studies have found sex category differences, with adolescent girls reporting more victimization than boys, particularly sexual violence. Sexual and gender minority youth also experience a higher prevalence of violence victimization than their heterosexual counterparts. Studies on risk factors include examinations of childhood adversities, exposure to sexually explicit material and substance use as well as the role of gender inequitable attitudes on violence perpetration. Recent prevention research includes examining the impact of bystander interventions and transforming gender norms. Recent ADV/ sexual violence research highlights both prevalence and modifiable risk and protective factors that may help reduce such violence. Practitioners caring for youth should consider ADV/ sexual violence when seeing patients (including those struggling with substance use and other behaviours that contribute to poor health) and not simply rely on screening tools to identify those suffering from ADV/ sexual violence.

  20. Adolescent beliefs about the acceptability of dating violence: does violent behavior change them?

    2013-01-01

    This longitudinal study examined the interplay between teens' beliefs about the acceptability of dating violence and dating violence perpetration. The final sample included 82 teens aged 14 to 17 years. Families were recruited from truancy courts and juvenile probation and victim services offices. Teens participated in a baseline and a follow-up assessment spaced 3 months apart. At each assessment, teens reported on their beliefs about dating violence acceptability and their dating violence perpetration. Dating violence perpetration at baseline predicted beliefs accepting of violence at follow-up, after accounting for baseline levels of beliefs. Beliefs at baseline, however, did not predict dating violence perpetration at follow-up. Dating violence perpetration may lead to beliefs more accepting of such violence.

  1. Mediating Factors Explaining the Association Between Sexual Minority Status and Dating Violence.

    Science.gov (United States)

    Martin-Storey, Alexa; Fromme, Kim

    2017-08-01

    Dating violence presents a serious threat for individual health and well-being. A growing body of literature suggests that starting in adolescence, individuals with sexual minority identities (e.g., individuals who identify as gay, lesbian, or bisexual) may be at an increased risk for dating violence compared with heterosexuals. Research has not, however, identified the mechanisms that explain this vulnerability. Using a diverse sample of young adults ( n = 2,474), the current study explored how minority stress theory, revictimization theory, sex of sexual partners, and risky sexual behavior explained differences in dating violence between sexual minority and heterosexual young adults. Initial analyses suggested higher rates of dating violence among individuals who identified as bisexual, and individuals who identified as gay or lesbian when compared with heterosexuals, and further found that these associations failed to differ across gender. When mediating and control variables were included in the analyses, however, the association between both sexual minority identities and higher levels of dating violence became nonsignificant. Of particular interest was the role of discrimination, which mediated the association between bisexual identity and dating violence. Other factors, including sex and number of sexual partners, alcohol use, and childhood maltreatment, were associated with higher rates of dating violence but did not significantly explain vulnerability among sexual minority individuals compared with their heterosexual peers. These findings suggest the importance of minority stress theory in explaining vulnerability to dating violence victimization among bisexuals in particular, and generally support the importance of sexual-minority specific variables in understanding risk for dating violence within this vulnerable population.

    2015-03-01

    Although interprofessional education (IPE) has existed in various formats for several decades, the need for IPE recently has taken on renewed interest and momentum. Public health has a critical role to play in furthering IPE, yet schools of public health are often underrepresented in IPE initiatives. The University of Iowa College of Public Health is serving as a catalyst for IPE activities on our health sciences campus, which includes colleges of dentistry, medicine, nursing, pharmacy, and public health. IPE-related activities have included campus visit by IPE leaders, administration of the Survey of Critical Elements for Implementing IPE, administration of the Interprofessional Learning Opportunities Inventory survey, the development of a comprehensive strategic plan, and the pilot of an IPE course for all first-year prelicensure students and Master of Health Administration students. Although more work is needed to more fully integrate IPE into the curriculum, success to date of the University of Iowa IPE initiative demonstrates that public health can play a critical role as a convener and catalyst for IPE curricular innovations on a health sciences campus.

  4. Building Public Confidence in Nuclear Activities

    2002-01-01

    Achieving public acceptance has become a central issue in discussions regarding the future of nuclear power and associated nuclear activities. Effective public communication and public participation are often put forward as the key building blocks in garnering public acceptance. A recent international workshop in Finland provided insights into other features that might also be important to building and sustaining public confidence in nuclear activities. The workshop was held in Finland in close cooperation with Finnish stakeholders. This was most appropriate because of the recent successes in achieving positive decisions at the municipal, governmental, and Parliamentary levels, allowing the Finnish high-level radioactive waste repository program to proceed, including the identification and approval of a proposed candidate repository site. Much of the workshop discussion appropriately focused on the roles of public participation and public communications in building public confidence. It was clear that well constructed and implemented programs of public involvement and communication and a sense of fairness were essential in building the extent of public confidence needed to allow the repository program in Finland to proceed. It was also clear that there were a number of other elements beyond public involvement that contributed substantially to the success in Finland to date. And, in fact, it appeared that these other factors were also necessary to achieving the Finnish public acceptance. In other words, successful public participation and communication were necessary but not sufficient. What else was important? Culture, politics, and history vary from country to country, providing differing contexts for establishing and maintaining public confidence. What works in one country will not necessarily be effective in another. Nonetheless, there appear to be certain elements that might be common to programs that are successful in sustaining public confidence and some of

  6. Using accelerator mass spectrometry for radiocarbon dating of textiles

    Energy Technology Data Exchange (ETDEWEB)

    Jull, A.J.T.

    1997-12-01

    Since 1981 we have operated an NSF Accelerator Mass Spectrometry (AMS) Facility at the University of Arizona. The AMS method allows us to use very small samples of carbon, <1 mg for radiocarbon dating in contrast to earlier counting techniques. This has opened a vast array of applications of radiocarbon dating that was difficult to do before AMS because of sample size limitations of decay counting. Some of the many applications of AMS include paleoclimatic studies, archaeological research and the age of first settlement of North America by man, dating of art works and artifacts, fall times and terrestrial residence ages of meteorites, production of {sup 14}C in lunar samples by galactic and solar cosmic rays, studies of in situ {sup 14}C produced by cosmic ray spallation in rocks and ice, and studies of {sup 14}C in groundwater dissolved inorganic carbon and dissolved organic carbon. At our laboratory, we have also successfully applied AMS {sup 14}C to dating of many types of textiles, including silks and linens, art works, documents and artifacts fabricated from wood, parchment, ivory, and bone. The results for many of these samples are often important in questions of the authenticity of these works of art and artifacts. Our studies have encompassed a wide range of art works ranging from the Dead Sea Scrolls, the Shroud of Turin, and the Chinese silk trade to the works of Raphael, Rembrandt, and Picasso. Recently, we also dated the Vinland Map, a controversial document that shows the eastern coast of North America apparently using information from Viking voyages.

  7. Progress in ESR dating of fossils

    International Nuclear Information System (INIS)

    Ikeya, M.

    1983-01-01

    In this review the progress of ESR dating is briefly described together with its historical development. Examples of fossil dating include shells and corals in geological sediments, fossil bones and teeth in anthropology and fossil woods in geology. The total dose of natural radiation (TD) equivalent to the archaeological dose in TL dating was obtained by the additive dose method. Initially, the TDs were plotted against the known ages; using the apparent annual dose-rate thus obtained gives the ESR age within a factor of 2 or 3 for a fossil. Precise assessment of the radiation environment was made later taking the disequilibrium of uranium series disintegration into account. ESR ages of corals agreed well with those obtained by radiocarbon and uranium-thorium methods. The time-independent accumulation rate or a linear accumulation or uranium was adopted as a first sensible model for the opensystem fossil bones: the relation between the TD and the age explains the ages of anthropologically important bones. Lastly, geological assessment of fossil woods was made by ESR based on the organic radicals and electron traps in the silicified part. (author)

  9. The establishment and development of the dating laboratory

    International Nuclear Information System (INIS)

    Nydal, R.

    1979-01-01

    Since the first dating was performed in 1956 on a piece of wood from the old Roman ship of Caligula, the lab. has done about 3000 datings. From 50-100 samples per year in the 1960s, it has now increased to about 450 samples each year. Besides 14 C dating work the purpose of the lab. is research and development in radiological dating. During the first years it was important to develop better proportional counters. The first counter, made of stainless steel from the periscope tube of a German submarine, had a total volume of 6 litres, and was too large for most of the samples. Later 14 C counters were of electrolytic copper and there are now 6 such counters in use, with total volumes from 0.6 to 2.1 litres. One of the largest has a recent standard net count of 18.5 c/min above a background of 0.60 c/min, and is capable of dating 50,000 year old samples. The accuracy of 14 C dating is dependent on how efficiently counters can be shielded against cosmic radiation and a special design of guard shell has been developed giving better protection than a system of single geiger tubes. Research has also included alternative dating methods. The thorium-uranium ratio in ocean carbonates may be a tool for extending beyond the limit for the 14 C method. The maximum age which theoretically can be determined is 300,000 years. Tritium studies have been performed on ice cores from glaciers in Jotunheimen and Spitzbergen. The lab. has also performed extended studies on the distribution of bomb produced 14 C from nuclear tests. (JIW)

  14. Neighborhood Factors and Dating Violence Among Youth: A Systematic Review.

    Science.gov (United States)

    Johnson, Renee M; Parker, Elizabeth M; Rinehart, Jenny; Nail, Jennifer; Rothman, Emily F

    2015-09-01

    The purpose of this review is to summarize the empirical research on neighborhood-level factors and dating violence among adolescents and emerging adults to guide future research and practice. In 2015, a total of 20 articles were identified through a search of the literature using PubMed. Eligible articles included those that (1) had been published in a peer-reviewed journal since 2005; (2) reported a measure of association between at least one neighborhood-level factor and dating violence; and (3) had a study population of youth aged dating violence and neighborhood factors, and measures of effect. Results were summarized into three categories based on the aspect of neighborhood that was the focus of the work: demographic and structural characteristics (n=11); neighborhood disorder (n=12); and social disorganization (n=8). There was some evidence to suggest that neighborhood disadvantage is associated with dating violence, but very little evidence to suggest that residence characteristics (e.g., racial heterogeneity) are associated with dating violence. Results do suggest that perceived neighborhood disorder is associated with physical dating violence perpetration, but do not suggest that it is associated with physical dating violence victimization. Social control and community connectedness are both associated with dating violence, but findings on collective efficacy are mixed. Existing research suggests that neighborhood factors may be associated with dating violence. However, there is a limited body of research on the neighborhood context of dating violence, and more rigorous research is needed. Copyright © 2015 American Journal of Preventive Medicine.

    This seventeenth list of accelerator dates consists mainly of material dated since the beginning of 1991, but includes a number of measurements made earlier in the dating programme. In accordance with international radiocarbon convention all dates are expressed in radiocarbon years before AD 1950 (years BP) using the half-life of 5568 years, this convention having been reaffirmed at the Trondheim Radiocarbon Conference 1985. Errors are quoted as one standard deviation and are based on an assessment of all the contributions to the error in the laboratory isotope ratio measurement. Natural fractionation of carbon isotopes is accounted for by estimating δ 13 C values except for more recent dates where δ 13 C have been measured relative to PDB (only to within ± 0.5-1.0%). All combining procedures and significance tests are based on Ward and Wilson (1978).

  16. ESR dating: is it still an 'experimental' technique?

    Skinner, A.R.

    2000-01-01

    Nearly 25 years ago, Motoji Ikeya demonstrated the potential of ESR dating. From a single substance (stalagmitic carbonate) and a single site (Akiyoshi Cavern), the field has grown to include materials from all over the world and time periods from a few thousand years ago to several million years ago. A vigorous program of instrumentation development has increased the precision of measurements as well as opening up new ways of collecting and interpreting spectra. Yet there are still references to ESR dating as an 'experimental' technique, one which cannot be trusted to produce dates that are accurate or precise. This paper discusses areas for which this is true and suggests what should be done to convince skeptics. Other areas for which the evidence suggests that ESR is at least as reliable as 'standard' methods will also be covered

    Using up-to-date archaeomagnetic data from Europe and CALS7K.2 as an apriori model, we produce a global geomagnetic field model to be used for archaeomagnetic dating in Europe. More details on the modelling process will be presented elsewhere (in session GP12, abstract: Geophysical insights from archaeomagnetic dating). Here we apply the global geomagnetic field model to a series of test cases from both recently published data and unpublished data to demonstrate its application to archaeomagnetic dating. We compare the results produced using our model with those from the spherical cap harmonic model, SCHA.DIF.3K (Pavón-Carrasco et al., 2009), the global geomagnetic field model, ARCH3K.1 (Korte et al., 2009) and those produced using the palaeosecular variation curves generated using Bayesian statistics (Lanos, 2004). We include examples which emphasise the importance of using three component data (declination, inclination and intensity) to produce an improved archaeomagnetic date. In addition to the careful selection of an appropriate model for archaeomagnetic dating, the choice of errors on the model curves is vital for providing archaeologists with an age range of possible dates. We discuss how best to constrain the errors on the model curves and alternative ways to the mathematical method of Lanos (2004) for producing an archaeomagnetic date for archaeologists.

    2013-02-01

    We randomly assigned the Shifting Boundaries interventions to 30 public middle schools in New York City, enrolling 117 sixth and seventh grade classes (over 2,500 students) to receive a classroom, a building, a combined, or neither intervention. The classroom intervention included a six-session curriculum emphasizing the laws and consequences for perpetrators of dating violence and sexual harassment (DV/H), the social construction of gender roles, and healthy relationships. The building-based intervention included the use of building-based restraining orders, higher levels of faculty/security presence in safe/unsafe "hot spots" mapped by students, and posters to increase DV/H awareness and reporting. Student surveys were implemented at baseline, immediately after the intervention, and 6-months post-intervention. As hypothesized, behaviors improved as a result of the interventions. The building-only and the combined interventions were effective in reducing sexual violence victimization involving either peers or dating partners at 6-months post-intervention. This was mirrored by reductions in sexual violence perpetration by peers in the building-only intervention. While the preponderance of results indicates that the interventions were effective, an anomalous result (increase in sexual harassment victimization reports that was contradicted by lower frequency estimates) did emerge. However, after analysis these anomalous results were deemed to be most likely spurious. The success of the building-only intervention alone is important because it can be implemented with very few extra costs to schools.

  1. Dating of cremated bones

    OpenAIRE

    Lanting, JN; Aerts-Bijma, AT; van der Plicht, J; Boaretto, E.; Carmi, I.

    2001-01-01

    When dating unburnt bone, bone collagen, the organic fraction of the bone, is used. Collagen does not survive the heat of the cremation pyre, so dating of cremated bone has been considered impossible. Structural carbonate in the mineral fraction of the bone, however, survives the cremation process. We developed a method of dating cremated bone by accelerator mass spectrometry (AMS), using this carbonate fraction. Here we present results for a variety of prehistoric sites and ages, showing a r...

  2. Using microwaves in Disinsection of dates

    The date palm plays a very significant role in Tunisia in term of culture as well as social, economic and ecological aspects. The production of the dates which is estimated to 120.000 tons/year ensures the principal income for the majority of the oasis population of the South of Tunisia and constitutes the basis for agricultural, industrial, commercial and tourist activities, offering million of working days. The date palm is cultivated mainly for the production of dates which are consumed locally or also exported abroad but for its by-products (food of the cattle, wind breaks, fuel, construction) which are marketed and/ or used in the everyday life thus taking part in the sedentarisation of the populations and the maintenance of a fragile socio-economic balance. The date moth, Ectomyelois ceratoniae Zell. ( L will epidoptera, Pyralidae) is without question the most significant problem of the Tunisian date palm. The infestation of dates in the field and in the storage and packing houses enormously depreciates the marketable quality of dates and risk to compromise exports in particular those of the variety Deglet Nour. rates of infestations of about 20% are often recorded in Tunisia where as the European standards require rates lower than 5%. In Tunisia the desinsectisation of dates is done until now by the use of methyl bromide, its high toxicity substantially reduces the duration of date treatment, and consequently the treated volumes. The replacement of this product becomes an urgent need its use will not be authorized by 2015. Within the framework of a agreement between the Regional Research Center in Oasis Agriculture (CRRAO), The Interprofessional Grouping of Fruits (GIF), and the Italian Company IMETEC, the use one of micro-waves as a desinsectisation method of dates was evaluated. The results of this present work showed that total desinsectisation of dates by microwaves can be obtained only with homogeneous dates in term of water content. Total

    The Bishop Tuff forms a key stratigraphic horizon for synchronization of Quaternary sedimentary records in North America. The unit stratigraphically overlies the Matuyama-Brunhes geomagnetic polarity reversal by several thousand years; high-precision dating of this tuff may be valuable for regional...... and global correlation of records. The Quaternary time scale is anchored by 40Ar/39Ar ages on lava flows and ash layers where available, with stage boundaries and geomagnetic reversals including astronomically tuned records. However, astronomical dating has not yet validated the high-precision 238U/206Pb...... ages, including new single crystal 40Ar/39Ar sanidine fusion analyses presented here, which demonstrates that concordance through multiple dating techniques is achievable within the Quaternary...

    Full Text Available The genetic modifications through breeding of crop plants have long been used to improve the yield and quality. However, precise genome editing (GE could be a very useful supplementary tool for improvement of crop plants by targeted genome modifications. Various GE techniques including ZFNs (zinc finger nucleases, TALENs (transcription activator-like effector nucleases, and most recently clustered regularly interspaced short palindromic repeats (CRISPR/Cas9 (CRISPR-associated protein 9-based approaches have been successfully employed for various crop plants including fruit trees. CRISPR/Cas9-based approaches hold great potential in GE due to their simplicity, competency, and versatility over other GE techniques. However, to the best of our knowledge no such genetic improvement has ever been developed in date palm—an important fruit crop in Oasis agriculture. The applications of CRISPR/Cas9 can be a challenging task in date palm GE due to its large and complex genome, high rate of heterozygosity and outcrossing, in vitro regeneration and screening of mutants, high frequency of single-nucleotide polymorphism in the genome and ultimately genetic instability. In this review, we addressed the potential application of CRISPR/Cas9-based approaches in date palm GE to improve the sustainable date palm production. The availability of the date palm whole genome sequence has made it feasible to use CRISPR/Cas9 GE approach for genetic improvement in this species. Moreover, the future prospects of GE application in date palm are also addressed in this review.

    2012-05-11

    The Food and Drug Administration (FDA) is delaying the compliance dates for the final rule for over-the-counter (OTC) sunscreen drug products that published in the Federal Register of June 17, 2011 (76 FR 35620). The final rule establishes labeling and effectiveness testing for certain OTC sunscreen products containing specified active ingredients and marketed without approved applications. It also amends labeling claims that are not currently supported by data and lifts the previously-published delay of implementation of the Drug Facts labeling requirements for OTC sunscreens. The 2011 final rule's compliance dates are being delayed because information received after publication of the 2011 final rule indicates that full implementation of the 2011 final rule's requirements for all affected products will require an additional 6 months. This final rule is part of FDA's ongoing review of OTC drug products.

  7. Influence of Seeding Ratio, Planting Date, and Termination Date on Rye-Hairy Vetch Cover Crop Mixture Performance under Organic Management.

    Directory of Open Access Journals (Sweden)

    Andrew Lawson

    Full Text Available Cover crop benefits include nitrogen accumulation and retention, weed suppression, organic matter maintenance, and reduced erosion. Organic farmers need region-specific information on winter cover crop performance to effectively integrate cover crops into their crop rotations. Our research objective was to compare cover crop seeding mixtures, planting dates, and termination dates on performance of rye (Secale cereale L. and hairy vetch (Vicia villosa Roth monocultures and mixtures in the maritime Pacific Northwest USA. The study included four seed mixtures (100% hairy vetch, 25% rye-75% hairy vetch, 50% rye-50% hairy vetch, and 100% rye by seed weight, two planting dates, and two termination dates, using a split-split plot design with four replications over six years. Measurements included winter ground cover; stand composition; cover crop biomass, N concentration, and N uptake; and June soil NO3(--N. Rye planted in mid-September and terminated in late April averaged 5.1 Mg ha(-1 biomass, whereas mixtures averaged 4.1 Mg ha(-1 and hairy vetch 2.3 Mg ha(-1. Delaying planting by 2.5 weeks reduced average winter ground cover by 65%, biomass by 50%, and cover crop N accumulation by 40%. Similar reductions in biomass and N accumulation occurred for late March termination, compared with late April termination. Mixtures had less annual biomass variability than rye. Mixtures accumulated 103 kg ha(-1 N and had mean C:N ratio <17:1 when planted in mid-September and terminated in late April. June soil NO3(--N (0 to 30 cm depth averaged 62 kg ha(-1 for rye, 97 kg ha(-1 for the mixtures, and 119 kg ha(-1 for hairy vetch. Weeds comprised less of the mixtures biomass (20% weeds by weight at termination compared with the monocultures (29%. Cover crop mixtures provided a balance between biomass accumulation and N concentration, more consistent biomass over the six-year study, and were more effective at reducing winter weeds compared with monocultures.

    The biggest island in South Korea is Jeju Island, which lies 80 km south of the mainland and has one shield volcano, Mt. Halla. The volcanic island and its lava tubes were added to the world heritage list by UNESCO in 2007. Among the many lava tubes on the island, a unique cave had been accidentally found in 2005 while some workers were replacing a telephone pole. Until the discovery, it had been completely isolated from the outside by naturally-built sand blocks. Yongcheon cave is a lime-decorated lava tube showing both the properties of a volcanic lava tube and a limestone cave. This cave, about 3 km in length, is acknowledged to be the best of this type in the world and includes a large clean-water lake, lava falls, and richly developed speleothems inside it. Even though there is archaeological evidence from well preserved pottery that ancient people entered this place, the preservation of artifacts was ensured by a geological change that made later entrance difficult. We have collected charcoal samples scattered around the cave and dated them using AMS. Ages were in the range of ca. 1570-1260 BP (A.D. 340–880) and this corresponds to the Ancient Three Kingdoms and the Unified Silla era in Korean history. The 14 C AMS measurement results presented in this paper on wood charcoal provide precise dates which will be very useful not only to clarify the nature of human activities in this cave but also to provide reference dates when comparing other dating methods.

  9. Chronic and Acute Relational Risk Factors for Dating Aggression in Adolescence and Young Adulthood.

    2016-04-01

    Dating aggression is a prevalent and costly public health concern. Using a relational risk framework, this study examined acute and chronic relational risk factors (negative interactions, jealousy, support, and relationship satisfaction) and their effects on physical and psychological dating aggression. The study also examined the interaction between chronic and acute risk, allowing us to assess how changes in acute risk have differing effects depending on whether the individual is typically at higher chronic risk. A sample of 200 youth (100 female) completed seven waves of data, which spanned 9 years from middle adolescence to young adulthood (M age at Wave 1 = 15.83). Using hierarchical linear modeling, analyses revealed both acute (within-person) and chronic (between-person) levels in jealousy, negative interactions, and relationship satisfaction, were associated with physical and psychological dating aggression. Significant interactions between chronic and acute risk emerged in predicting physical aggression for negative interactions, jealousy, and relationship satisfaction such that those with higher levels of chronic risk are more vulnerable to increases in acute risk. These interactions between chronic and acute risk indicate that risk is not static, and dating aggression is particularly likely to occur at certain times for youth at high risk for dating aggression. Such periods of increased risk may provide opportunities for interventions to be particularly effective in preventing dating aggression or its consequences. Taken together, these findings provide support for the role of relational risk factors for dating aggression. They also underscore the importance of considering risk dynamically.

  10. Effectiveness of "shifting boundaries" teen dating violence prevention program for subgroups of middle school students.

    2015-02-01

    We examine whether the Shifting Boundaries (SB) intervention, a primary intervention to prevent youth dating violence and sexual harassment (DV/H), is differentially effective for girls compared with boys or for youth with a history of DV/H experiences. We randomly assigned SB to 30 public middle schools in New York City, enrolling 117 sixth and seventh grade classes to receive a classroom, building, combined, or neither intervention. The SB classroom intervention included six sessions emphasizing the laws/consequences of DV/H, establishing boundaries and safe relationships. The SB schoolwide/building intervention included the use of school-based restraining orders, greater faculty/security presence in unsafe "hot spots" mapped by students, and posters to increase DV/H awareness and reporting. Student surveys were implemented at baseline, immediately after intervention, and 6 months after intervention. At 6 months after intervention, the SB building-level intervention was associated with significant reductions in the frequency of sexual harassment (SH) perpetration and victimization; the prevalence and frequency of sexual dating violence victimization; and the frequency of total dating violence victimization and perpetration. We also had one anomalous finding that the interventions were associated with an increase in the prevalence of SH victimization. These results were consistent for girls and boys, and those with or without a history of DV/H, with the one exception for those exposed to the SB building condition who had earlier reported perpetrating SH had a significantly lower frequency of perpetrating SH at the follow-up than those without such a history. SB can provide effective universal prevention of middle school DV/H experiences, regardless of students' prior exposure histories, and for boys and girls.

  11. Thermoluminescence dating

    International Nuclear Information System (INIS)

    Price, D.M.

    1999-01-01

    Thermoluminescence (TL) dating of sediments depends upon the acquisition and long term stable storage of TL energy by crystalline minerals contained within a sedimentary unit. This energy is stored in the form of trapped electrons and quartz sand is the most commonly used mineral employed in the dating process. Prior to the final depositional episode it is necessary that any previously acquired TL is removed by exposure to sunlight. After burial the TL begins to build up again at a rate dependent upon the radiation flux delivered by long-lived isotopes of uranium, thorium and potassium. The presence of rubidium and cosmic radiation generally play a lesser but contributory roll, and the total radiation dose delivered to the TL phosphor is modified by the presence of water. The period since deposition is therefore measured by determining the total amount of stored TL energy, the palaeodose (P), and the rate at which this energy is acquired, the annual radiation dose (ARD). TL dating may be applied to eolian, fluvial, coastal and in some cases, marine sediments. the technique is also successfully applied to volcanic materials and to a certain extent to archeological specimens

    The paper concerns the use of dendrochronology to check the accuracy of radiocarbon dating. The Belfast chronology is described - this involves wood samples precisely dated by tree ring analysis and analysed by high-precision radiocarbon analysis. The analysis resulted in the first continuous high-precision calibration of the radiocarbon time-scale, and confirmed the relationship between radiocarbon dates and tree-ring dates. The use of radiocarbon dating to reveal the age of wood samples that have too few rings to produce an accurate date, is also outlined. (U.K.)

    We examined the association between witnessing interparental violence, attitudes about dating violence, and physical and psychological teen dating violence (TDV) victimization. Participants were 918 teens with dating experience. Witnessing interparental violence and acceptance of dating violence were significant predictors of TDV victimization. Acceptance of dating violence was also a partial mediator between witnessing interparental violence and TDV victimization. Witnessing mother-to-father violence and acceptance of female-perpetrated violence were the most consistent predictors. TDV programs aiming to prevent victimization could benefit from targeting youth exposed to father-to-mother and mother-to-father violence, targeting attitudes about violence, and tailoring interventions to gender-specific risk factors. © The Author(s) 2015.

  18. AMS Radiocarbon Dating at Notre Dame

    Howard, Sean

    2014-09-01

    Current development of a local radiocarbon dating method using Accelerator Mass Spectrometry (AMS) at the University of Notre Dame seeks to provide sensitive, reproducible, and accurate measurements for future interdisciplinary projects. While AMS has been the premier radiocarbon dating method for a few decades, repurposing Notre Dame's FN Tandem accelerator for radiocarbon dating has provided many unique challenges. Experiments have shown radiocarbon dating possible and reproducible using the FN Tandem accelerator, found optimal settings for said accelerator, and established sensitivity limits comparable to dedicated radiocarbon dating facilities. In addition, there is ongoing work to create a local chemistry lab to convert organic artifacts into graphite samples to be dated locally. Once the chemistry side has been completed, several artifacts from the IAEA's radiocarbon intercomparison have been procured. Dating these previously studied artifacts will provide an additional measure on the accuracy and repeatability of both the accelerator and chemical treatment. Provided that these IAEA artifacts are dated successfully, exciting projects will ensue, such as the authentication of artwork and dating of anthropological samples.

  19. Total-Evidence Dating under the Fossilized Birth-Death Process.

    2016-03-01

    Bayesian total-evidence dating involves the simultaneous analysis of morphological data from the fossil record and morphological and sequence data from recent organisms, and it accommodates the uncertainty in the placement of fossils while dating the phylogenetic tree. Due to the flexibility of the Bayesian approach, total-evidence dating can also incorporate additional sources of information. Here, we take advantage of this and expand the analysis to include information about fossilization and sampling processes. Our work is based on the recently described fossilized birth-death (FBD) process, which has been used to model speciation, extinction, and fossilization rates that can vary over time in a piecewise manner. So far, sampling of extant and fossil taxa has been assumed to be either complete or uniformly at random, an assumption which is only valid for a minority of data sets. We therefore extend the FBD process to accommodate diversified sampling of extant taxa, which is standard practice in studies of higher-level taxa. We verify the implementation using simulations and apply it to the early radiation of Hymenoptera (wasps, ants, and bees). Previous total-evidence dating analyses of this data set were based on a simple uniform tree prior and dated the initial radiation of extant Hymenoptera to the late Carboniferous (309 Ma). The analyses using the FBD prior under diversified sampling, however, date the radiation to the Triassic and Permian (252 Ma), slightly older than the age of the oldest hymenopteran fossils. By exploring a variety of FBD model assumptions, we show that it is mainly the accommodation of diversified sampling that causes the push toward more recent divergence times. Accounting for diversified sampling thus has the potential to close the long-discussed gap between rocks and clocks. We conclude that the explicit modeling of fossilization and sampling processes can improve divergence time estimates, but only if all important model aspects

  20. Optical stimulated luminescence (OSL) dating

    International Nuclear Information System (INIS)

    Banerjee, D.

    1999-01-01

    Since the pioneering work by Huntley et al. (1985), optical dating is being increasingly recognised as an important technique for establishing a time frame of deposition of sediments (Aitken, 1998). Optical dating differs from thermoluminescence (TL) dating in that visible/infrared light from lasers or LEDs (light-emitting-diodes) is used as a means of stimulation, in contrast to thermal stimulation. It has several advantages over TL dating: (i) the resetting of the OSL (optically stimulated luminescence) clock is more effective than that of TL clock; for sediments transported under water or in other situations where the sediment grains have undergone inhomogeneous bleaching, this property ensures that ages based on optical dating are generally more reliable than TL ages, (ii) the optical dating technique is non-destructive, and multiple readouts of the optical signal is possible; this feature has resulted in the development of single-aliquot and single-grain protocols (Murray and Wintle, 1999; Banerjee et al. 1999), (iii) the sample is not heated as in TL; thus, spurious luminescence is avoided and there is a significant reduction in blackbody radiation. Dating of materials which change phase on heating is also practical, and finally, (iv) thermal quenching of luminescence is negligible, allowing accurate estimation of kinetic parameters using standard techniques and providing access to deep OSL traps. This characteristic may be helpful in extending the limits of optical dating beyond the last 150 ka from a global point of view

    Alcock, Nathaniel W

    2017-11-17

    The techniques of dendrochronology (tree-ring dating) and radiocarbon (14C) dating are described, as they are applied to historic buildings. Both rely on determining the felling dates of the trees used in their construction. For dendrochronology, the construction of master chronologies and the matching of individual ring-width sequences to them is described and, for radiocarbon dating, the use of tree-ring results in calibration. Results of dating are discussed, ranging from the cathedrals of Peterborough and Beauvais and the development of crown-post roof structures, to the dating and identification of standing medieval peasant houses, particularly those built using cruck construction.

    2013-01-01

    This paper synthesises and discusses results from the 2005 Survey of Student Well-Being, a closed-ended questionnaire administered to students attending general education courses at a major public university in Santiago (n = 484 women, 466 men). The survey included questions on sexual violence (SV) and dating violence (DV), public health problems that have received little attention in Chile and other Latin-American countries. This paper highlights key findings from a series of papers based on these data, noting lessons learned in the Chilean context that may be useful for other Latin-American countries. Important gaps in the international literature on SV and DV are also discussed. A central finding is the high prevalence of SV and DV in this sample of university students, warranting further public health attention to these problems. Potentially, the findings will contribute to changes in awareness, policy and practice along similar lines to efforts that transformed the US landscape regarding SV and DV on college campuses in the 1980s.

  8. Quantity of dates trumps quality of dates for dense Bayesian radiocarbon sediment chronologies - Gas ion source 14C dating instructed by simultaneous Bayesian accumulation rate modeling

    Radiocarbon (14C) sediment core chronologies benefit from a high density of dates, even when precision of individual dates is sacrificed. This is demonstrated by a combined approach of rapid 14C analysis of CO2 gas generated from carbonates and organic material coupled with Bayesian statistical modeling. Analysis of 14C is facilitated by the gas ion source on the Continuous Flow Accelerator Mass Spectrometry (CFAMS) system at the Woods Hole Oceanographic Institution's National Ocean Sciences Accelerator Mass Spectrometry facility. This instrument is capable of producing a 14C determination of +/- 100 14C y precision every 4-5 minutes, with limited sample handling (dissolution of carbonates and/or combustion of organic carbon in evacuated containers). Rapid analysis allows over-preparation of samples to include replicates at each depth and/or comparison of different sample types at particular depths in a sediment or peat core. Analysis priority is given to depths that have the least chronologic precision as determined by Bayesian modeling of the chronology of calibrated ages. Use of such a statistical approach to determine the order in which samples are run ensures that the chronology constantly improves so long as material is available for the analysis of chronologic weak points. Ultimately, accuracy of the chronology is determined by the material that is actually being dated, and our combined approach allows testing of different constituents of the organic carbon pool and the carbonate minerals within a core. We will present preliminary results from a deep-sea sediment core abundant in deep-sea foraminifera as well as coastal wetland peat cores to demonstrate statistical improvements in sediment- and peat-core chronologies obtained by increasing the quantity and decreasing the quality of individual dates.

    Complete text of publication follows: Estimates of groundwater age allow geo-hydrologists to calculate recharge rates, assess aquifers contamination risks, and calibrate complex flow models. The {sup 3}H/{sup 3}He dating method offers a direct measure for the time since groundwater had its last gas exchange with the atmosphere. The aim of this study is to bring temporal constraints to the radionuclide transport model in the Chernobyl test site. Samples have been collected in the exclusion zone, close to a trench filled with low-level wastes, both in the upper eolian sand layer and deeper in the alluvial deposit. CFCs and SF6 have been measured as well in order to compare dating methods. The {sup 3}H/{sup 3}He results presented in Figure 1 clearly show increasing ages with depth (below groundwater table). This fully supports the groundwater stratification developed in the hydrogeological model of the area. The infiltration recharge rate is a sensitive key parameter of the model, and our data are consistent with a rate about 200 mm/yr (maximum estimate)

    Little is known about the extent and nature of publication bias in economic evaluations. Our objective was to determine whether economic evaluations are subject to publication bias by considering whether economic data are as likely to be reported, and reported as promptly, as effectiveness data. Trials that intended to conduct an economic analysis and ended before 2008 were identified in the International Standard Randomised Controlled Trial Number (ISRCTN) register; a random sample of 100 trials was retrieved. Fifty comparator trials were randomly drawn from those not identified as intending to conduct an economic study. The trial start and end dates, estimated sample size and funder type were extracted. For trials planning economic evaluations, effectiveness and economic publications were sought; publication dates and journal impact factors were extracted. Effectiveness abstracts were assessed for whether they reached a firm conclusion that one intervention was most effective. Primary investigators were contacted about reasons for non-publication of results, or reasons for differential publication strategies for effectiveness and economic results. Trials planning an economic study were more likely to be funded by government (p = 0.01) and larger (p = 0.003) than other trials. The trials planning an economic evaluation had a mean of 6.5 (range 2.7-13.2) years since the trial end in which to publish their results. Effectiveness results were reported by 70 %, while only 43 % published economic evaluations (p economic results included the intervention being ineffective, and staffing issues. Funding source, time since trial end and length of study were not associated with a higher probability of publishing the economic evaluation. However, studies that were small or of unknown size were significantly less likely to publish economic evaluations than large studies (p journal impact factor was 1.6 points higher for effectiveness publications than for the

    Teen dating violence (TDV), bullying, and HIV risk behaviors are public health concerns that impact adolescents in the United States. National estimates reveal high rates of these risk behaviors among high school students. Based on theoretical and empirical evidence, we hypothesized that experiencing teen dating violence (sexual and physical) would mediate the impact of bullying on HIV risk. Data were from the 2013 National Youth Behavior Risk Surveillance Survey (YRBSS) among students who answered questions on bullying, TDV, and HIV risk (N = 13,571). The YRBSS is conducted biennially among 9th- to 12th-grade students nationally. We used multiple regression analysis and Hayes' SPSS process macro to examine the 2 study hypotheses. Findings from bivariate analysis suggest an association between bullying and HIV risk. The study also found associations between physical, sexual teen dating violence and HIV risk. Results also indicate that both physical and sexual teen dating violence mediate the association between bullying and HIV risk. Our findings suggest that multidimensional interventions should be developed to reduce the rate of teen dating violence and combat bullying as a preventative method for HIV risk among high school students. © 2017, American School Health Association.

  13. How AMS dating changed my life

    International Nuclear Information System (INIS)

    Spriggs, M.

    2001-01-01

    Accelerator mass spectrometry (AMS) radiocarbon dating was developed in the late 1970s. Remembering back to a time before AMS dating was available to archaeologists is a bit like trying to remember how we ever survived without desktop computers, email or automatic teller machines. My own particular interest in AMS dating was an inevitable offshoot from my long-established interest in chronometric hygiene, or 'getting the dates right'. In this paper I attempt to illustrate that accurate dating matters, by discussing some examples of AMS dating projects with which I have been involved over the last six years or so. In relation to these projects, AMS has given us the ability to date sites which we could not before. It has enabled us to provide more detailed stratigraphies when datable materials are rare. It has allowed us to date materials we could not date before, such as rock art pigments. It has been able to provide indications of the degree of site disturbance in the absence of other obvious forms of evidence. And it has allowed us to assess claims for the antiquity of particular material cultural types and faunal introductions. (author). 41 refs

    In this paper, radiocarbon dating of paintings using minimal sample sizes has been investigated, in an effort to address the problem of limited access to sample material in paintings. 14 C analyses were conducted on signed and dated paintings from two Swiss artists of the twentieth century. The selected paintings dated from the 1930s and 1960s, provided the opportunity to evaluate the dating accuracy on paintings realized before and after 1950 AD when the 14 C bomb peak was created, as a result of the nuclear tests conducted in the 1950/1960s. The work focused on the one hand on minimizing the size of the canvas sample required for accelerator mass spectrometer radiocarbon measurement on the gas ion source of the MICADAS and, on the other hand, on testing the possibility of dating the organic binder of the paint. Following careful characterization of the paint composition by X-ray fluorescence spectroscopy, Fourier transformed infrared spectroscopy, and Raman spectroscopy, paints containing no other carbon source than the natural organic binder were identified and dated.

    2014-06-01

    The scope of this paper is to describe characteristics of the scientific output in the area of public oral health in journals on public health and dentistry nationwide. The Scopus database of abstracts and quotations was used and eight journals in public health, as well as ten in dentistry, dating from 1947 to 2011 were selected. A research strategy using key words regarding oral health in public health and key words about public health in dentistry was used to locate articles. The themes selected were based on the frequency of key words. Of the total number of articles, 4.7% (n = 642) were found in oral health journals and 6.8% (n = 245) in public health journals. Among the authors who published most, only 12% published in both fields. There was a percentile growth of public oral health publications in dentistry journals, though not in public health journals. In dentistry, only studies indexed as being on the topic of epidemiology showed an increase. In the area of public health, planning was predominant in all the phases studied. Research to evaluate the impact of research and postgraduate policies in scientific production is required.

    Date palm has been a major fruit tree in the Middle East over thousands of years, especially in the Arabian Peninsula. Dates are consumed fresh (Rutab) or after partial drying and storage (Tamar) during off-season. The aim of the study was to provide in-depth analysis of fungal communities associated with the skin (outer part) and mesocarp (inner fleshy part) of stored dates (Tamar) of two cultivars (Khenizi and Burny) through the use of Illumina MiSeq sequencing. The study revealed the dominance of Ascomycota (94%) in both cultivars, followed by Chytridiomycota (4%) and Zygomycota (2%). Among the classes recovered, Eurotiomycetes, Dothideomycetes, Saccharomycetes and Sordariomycetes were the most dominant. A total of 54 fungal species were detected, with species belonging to Penicillium, Alternaria, Cladosporium and Aspergillus comprising more than 60% of the fungal reads. Some potentially mycotoxin-producing fungi were detected in stored dates, including Aspergillus flavus, A. versicolor and Penicillium citrinum, but their relative abundance was very limited (PerMANOVA analysis revealed the presence of insignificant differences in fungal communities between date parts or date cultivars, indicating that fungal species associated with the skin may also be detected in the mesocarp. It also indicates the possible contamination of dates from different cultivars with similar fungal species, even though if they are obtained from different areas. The analysis shows the presence of different fungal species in dates. This appears to be the first study to report 25 new fungal species in Oman and 28 new fungal species from date fruits. The study discusses the sources of fungi on dates and the presence of potentially mycotoxin producing fungi on date skin and mesocarp.

  20. History of dating violence and the association with late adolescent health

    2013-01-01

    Background The present investigation expands upon prior studies by examining the relationship between health in late adolescence and the experience of physical/sexual and non-physical dating violence victimization, including dating violence types that are relevant to today’s adolescents (e.g., harassment via email and text messaging). We examined the relationship between physical/sexual and non-physical dating violence victimization from age 13 to 19 and health in late adolescence/early adulthood. Methods The sample comprised 585 subjects (ages 18 to 21; mean age, 19.8, SD = 1.0) recruited from The Ohio State University who completed an online survey to assess: 1) current health (depression, disordered eating, binge drinking, smoking, and frequent sexual behavior); and 2) dating violence victimization from age 13 to 19 (retrospectively assessed using eight questions covering physical, sexual, and non-physical abuse, including technology-related abuse involving stalking/harassment via text messaging and email). Multivariable models compared health indicators in never-exposed subjects to those exposed to physical/sexual or non-physical dating violence only. The multivariable models were adjusted for age and other non-dating abuse victimization (bullying; punched, kicked, choked by a parent/guardian; touched in a sexual place, forced to touch someone sexually). Results In adjusted analyses, compared to non-exposed females, females with physical/sexual dating violence victimization were at increased risk of smoking (prevalence ratio = 3.95); depressive symptoms (down/hopeless, PR = 2.00; lost interest, PR = 1.79); eating disorders (using diet aids, PR = 1.98; fasting, PR = 4.71; vomiting to lose weight, PR = 4.33); and frequent sexual behavior (5+ intercourse and oral sex partners, PR = 2.49, PR = 2.02; having anal sex, PR = 2.82). Compared to non-exposed females, females with non-physical dating violence only were at increased risk of smoking (PR = 3

    The application of radiocarbon dating techniques for pedological purposes is reviewed in chronological sequence of its phases of introduction. Initially dating of charcoal and buried paleosols was dominating and accompanied by few soil dating attempts of recent soil formations on the basis of extracted humic acid-C. The following controversy regarding the potentialities and limitations of recent soil dating, still being involved in the intact turnover processes of modern biodynamics, led to intensive search for the relatively oldest, most favorable C-fraction, particularly a biologically inert C-fraction of the organic C-pool. Inclusion of C-14 dating in pedogenetic working concepts required soil profile date-scanning in order to reveal the age versus depth interdependence. (orig./HK) [de

    When dating unburnt bone, bone collagen, the organic fraction of the bone, is used. Collagen does not survive the heat of the cremation pyre, so dating of cremated bone has been considered impossible. Structural carbonate in the mineral fraction of the bone, however, survives the cremation process.

The groups of high-risk young women in this review include street-involved, justice-involved, pregnant or parenting, involved with Child Protective Services, and youth diagnosed with a mental health issue. Our meta-analysis of the quantitative articles indicated that 34% (CI = 0.24–0.45) of high-risk young women report that they have been victims of physical dating violence and 45% (CI = 0.31–0.61) of these young women report perpetrating physical dating violence. Significant moderator variables included questionnaire and timeframe. Meta-synthesis of the qualitative studies revealed that high-risk young women report perpetrating dating violence to gain power and respect, whereas women report becoming victims of dating violence due to increased vulnerability.

    The application of the radiocarbon dating in archaeology has not served only to solve problems related with the establishment of chronologies, but also in the development of archaeological methods of excavation and interpretation. This has been possible because the dating method by radiocarbon provides a common temporary scale that transcends the cultural and regional frontiers. It is even spoken of the revolution that has meant the fact that the application of this method has allowed to the archaeologist to pass from the construction of chronologies until the evaluation and dynamic interpretation of the archaeological data to build theories. This work explains and compares methods for the detection of 14 C, as the gas counting, the liquid scintillation counting and the mass spectrometry with accelerators. (Author)

    Date rape (DR) is a serious but under-recognized public health problem that affects female university undergraduates. The burden of the problem in Nigerian universities is, however, yet to be fully investigated. The study was designed to explore the physical and psycho-social experiences of DR female survivors at the University of Ibadan. The study was qualitative in nature and involved eight consenting DR survivors. A pre-tested In-Depth Interview (IDI) guide that included questions relating to survivors' personal profile, context of DR experienced, factors that promoted survivors' vulnerability, reported adverse health consequences, help-seeking behaviors, and effects of the rape episode on dating relationship was used to facilitate the conduct of the narrative interview. The interviews were conducted in accordance to the protocol approved by the Joint University of Ibadan and University College Hospital Ethics Review Committee, and were taped-recorded and subjected to content analysis. Participants' mean age was 17.3 ± 2.3 years. All the participants were teenagers when they were first raped. Coercive and deceptive means were used to perpetrate the act of rape. Participants' use of verbal appeals, crying, and physical resistance to prevent being raped proved abortive. The experienced adverse physical health consequences included vaginal bleeding and injury. Major psycho-social effects of the experienced DR included self-blame, depression, hatred for men, and suicidal feelings. DR experiences occurred mainly in isolated settings, and most participants could not seek for medical help and other forms of care due to fear of being stigmatized. Some of the DR survivors continued their dating relationships when apologies were tendered by the perpetrators. DR is a traumatic experience, which is characterized by physical and psycho-social adverse effects. DR survivors, however, rarely seek for help as a result of the fear of being stigmatized.

    The aim of this study was to assess the reciprocal associations among social information processing (SIP) in dating conflicts and the perpetration of dating aggression. A first step involved the development of a measure (The Social Information Processing Questionnaire in Dating Conflicts, SIPQ-DC) to assess social information in scenarios of conflict with dating partners. A sample of 1,272 adolescents (653 girls, 619 boys; Mage = 14.74 years, SD = 1.21) completed measures of SIP and dating aggression perpetration in two different times, which were spaced 1 year apart. Confirmatory factor analyses provided support for a model with five correlated factors for the SIPQ-DC, namely, hostile attribution, anger, aggressive response access, anticipation of positive consequences for oneself, and anticipation of negative consequences for partners. Although the perpetration of dating aggression at T1 was cross-sectionally associated with all the SIP components, anger was the only component that predicted the residual increase in dating aggression behavior over time. The perpetration of dating aggression predicted a worsening of cognitive-emotional processes involved in dating conflicts. Some longitudinal paths were significant only in male adolescents. In conclusion, relationships among SIP and aggression are reciprocal. Gender differences in longitudinal paths can contribute to explaining men's higher perpetration of violence in adulthood. © The Author(s) 2014.

    2016-07-01

    Teen dating violence is a serious public health problem. A cluster-randomized trial was conducted to assess the efficacy of Teen Choices , a 3-session online program that delivers assessments and individualized guidance matched to dating history, dating violence experiences, and stage of readiness for using healthy relationship skills. For high risk victims of dating violence, the program addresses readiness to keep oneself safe in relationships. Twenty high schools were randomly assigned to the Teen Choices condition ( n =2,000) or a Comparison condition ( n =1,901). Emotional and physical dating violence victimization and perpetration were assessed at 6 and 12 months in the subset of participants (total n =2,605) who reported a past-year history of dating violence at baseline, and/or who dated during the study. The Teen Choices program was associated with significantly reduced odds of all four types of dating violence (adjusted ORs ranging from .45 to .63 at 12 months follow-up). For three of the four violence outcomes, participants with a past-year history of that type of violence benefited significantly more from the intervention than students without a past-year history. The Teen Choices program provides an effective and practicable strategy for intervention for teen dating violence prevention.

  16. Obsidian dating prospects

    International Nuclear Information System (INIS)

    Ambrose, W.

    1997-01-01

    Full text: Developments in the nuclear industry have shown that some of the problems related to the glassification of waste for long term storage are centred on the rate of glass weathering in various repositories. Long term weathering of artificial glasses is paralleled by the archaeological problem of determining hydration rates in obsidian artefacts as a means of dating their manufacture. Figures available for sites in Papua New Guinea indicate that the weathering rate is sufficiently fast to render conventional hydration measurement completely unreliable. This follows from the range of calculated surface reduction rates which range between .0002μ to .004μ per year depending on the site's location and the obsidian source. Hydration rates for key Papua New Guinea obsidians have been determined from long term experimental laboratory exposure and these are used to evaluate the age of obsidians from selected archaeological sites. By adopting a strategy of measuring hydration in concealed fissures both the weathering rate and the dating of the Papua New Guinea obsidians have been successfully achieved. The dissolution rates of natural obsidians could be useful in considering weathering rates for artificial glasses. An improved system for calculating the annual effective hydration temperature is presented which gives a better control of micro-environmental temperature in its crucial rate determining role. The combined result of these developments gives obsidian hydration dating an enhanced capacity to be a useful and independent dating system

  17. The Schmidt hammer as a relative-age dating tool and its potential for calibrated-age dating in Holocene glaciated environments

    Science.gov (United States)

    Shakesby, Richard A.; Matthews, John A.; Owen, Geraint

    2006-11-01

    The Schmidt hammer is a relatively cheap, portable, sturdy instrument with proven value over the last two decades or so in rapidly dating coarse inorganic deposits of diverse origins. Early views were that its dating role was limited to distinguishing recently exposed from much older. Typically, either a few sites of possibly different ages or occasional older surfaces amongst many young sites were studied. More recently, calibration curves based on individual R-value means from small numbers (2-4) of sites of known ages have been used to estimate the ages of undated sites. We present Schmidt hammer rebound ( R-) values from 28 'Little Ice Age' (and younger), 23 Preboreal and 7 Younger Dryas glaciated surfaces in southern Norway in order, first, to test rigorously the robustness of the instrument as a relative-age dating tool. Despite being obtained from different surfaces (moraines, glaciofluvial deposits and bedrock) and varied metamorphic lithologies, the R-value overall means and 95% confidence intervals for the 'Little Ice Age', Preboreal and Younger Dryas age categories (respectively, 60.0±1.6, 41.6±1.4 and 34.2±2.0) are statistically significantly different. Only two outlying sites in the two younger age categories have overlapping confidence intervals, demonstrating remarkable robustness in differentiating early- and late-Holocene surfaces. The distinction between Preboreal and Younger Dryas sites (with terminal dates factors, including some previously considered critical (instrument wear, operator bias, initial rock surface texture), which emerge either as less important than previously argued or as relatively unimportant, together with others previously unreported (e.g. long-term changes in lichen, soil, snow and vegetation covers). Third, we investigate the potential for calibrated-age dating by applying exploratory, linear rates of R-value decline to selected combinations of sites. The results suggest that error limits of ca ±700 to ±1600 years

  19. Where Dating Meets Data: Investigating Social and Institutional Privacy Concerns on Tinder

    Directory of Open Access Journals (Sweden)

    Christoph Lutz

    2017-03-01

    Full Text Available The widespread diffusion of location-based real-time dating or mobile dating apps, such as Tinder and Grindr, is changing dating practices. The affordances of these dating apps differ from those of “old school” dating sites, for example, by privileging picture-based selection, minimizing room for textual self-description, and drawing upon existing Facebook profile data. They might also affect users’ privacy perceptions as these services are location based and often include personal conversations and data. Based on a survey collected via Mechanical Turk, we assess how Tinder users perceive privacy concerns. We find that the users are more concerned about institutional privacy than social privacy. Moreover, different motivations for using Tinder—hooking up, relationship, friendship, travel, self-validation, and entertainment—affect social privacy concerns more strongly than institutional concerns. Finally, loneliness significantly increases users’ social and institutional privacy concerns, while narcissism decreases them.

    The biggest island in South Korea is Jeju Island, which lies 80 km south of the mainland and has one shield volcano, Mt. Halla. The volcanic island and its lava tubes were added to the world heritage list by UNESCO in 2007. Among the many lava tubes on the island, a unique cave had been accidentally found in 2005 while some workers were replacing a telephone pole. Until the discovery, it had been completely isolated from the outside by naturally-built sand blocks. Yongcheon cave is a lime-decorated lava tube showing both the properties of a volcanic lava tube and a limestone cave. This cave, about 3 km in length, is acknowledged to be the best of this type in the world and includes a large clean-water lake, lava falls, and richly developed speleothems inside it. Even though there is archaeological evidence from well preserved pottery that ancient people entered this place, the preservation of artifacts was ensured by a geological change that made later entrance difficult. We have collected charcoal samples scattered around the cave and dated them using AMS. Ages were in the range of ca. 1570-1260 BP (A.D. 340-880) and this corresponds to the Ancient Three Kingdoms and the Unified Silla era in Korean history. The {sup 14}C AMS measurement results presented in this paper on wood charcoal provide precise dates which will be very useful not only to clarify the nature of human activities in this cave but also to provide reference dates when comparing other dating methods.

    2013-01-01

    Global climate model outputs involve uncertainties in prediction, which could be reduced by identifying agreements between the output results of different models, covering all assumptions included in each. Fusarium oxysporum f.sp. is an invasive pathogen that poses risk to date palm cultivation, among other crops. Therefore, in this study, the future distribution of invasive Fusarium oxysporum f.sp., confirmed by CSIRO-Mk3.0 (CS) and MIROC-H (MR) GCMs, was modeled and combined with the future distribution of date palm predicted by the same GCMs, to identify areas suitable for date palm cultivation with different risk levels of invasive Fusarium oxysporum f.sp., for 2030, 2050, 2070 and 2100. Results showed that 40%, 37%, 33% and 28% areas projected to become highly conducive to date palm are under high risk of its lethal fungus, compared with 37%, 39%, 43% and 42% under low risk, for the chosen years respectively. Our study also indicates that areas with marginal risk will be limited to 231, 212, 186 and 172 million hectares by 2030, 2050, 2070 and 2100. The study further demonstrates that CLIMEX outputs refined by a combination of different GCMs results of different species that have symbiosis or parasite relationship, ensure that the predictions become robust, rather than producing hypothetical findings, limited purely to publication.

  7. Public information circular for shipments of irradiated reactor fuel. Revision 5

    International Nuclear Information System (INIS)

    1985-06-01

    This circular has been prepared in response to numerous requests for information regarding routes used for the shipment of irradiated reactor (spent) fuel subject to regulation by the Nuclear Regulatory Commission (NRC), and to meet the requirements of Public Law 96-295. The NRC staff must approve such routes prior to their first use in accordance with the regulatory provisions of Section 73.37 of 10 CFR Part 73. The information included reflects NRC staff knowledge as of June 1, 1985. Spent fuel shipment routes, primarily for road transportation, but also including one rail route, are indicated on reproductions of DOT road maps. Also included are the amounts of material shipped during the approximate three year period that safeguards regulations for spent fuel shipments have been effective. In addition, the Commission has chosen to provide information in this document regarding the NRC's safety and safeguards regulations for spent fuel shipment as well as safeguards incidents regarding spent fuel shipments (of which none have been reported to date). This additional information is furnished by the Commission in order to convey to the public a more complete picture of NRC regulatory practices concerning the shipment of spent fuel than could be obtained by the publication of the shipment routes and quantities alone

  8. Predictors of dating violence among Chinese adolescents: the role of gender-role beliefs and justification of violence.

    Shen, April Chiung-Tao; Chiu, Marcus Yu-Lung; Gao, Jianxiu

    2012-04-01

    In Chinese societies, violence among adolescent dating partners remains a largely ignored and invisible phenomenon. The goal of this study is to examine the relationships among gender-role beliefs, attitudes justifying dating violence, and the experiences of dating-violence perpetration and victimization among Chinese adolescents. This study has used self-reporting measures to collect data from a probability sample of 976 adolescents (mean age = 15.9) in three Chinese societies: Taiwan, Hong Kong, and Shanghai. Research results reveal a high prevalence of dating violence (including physical violence, sexual violence, and controlling behavior) among Chinese adolescents with dating experience: the perpetration rate is 27.3% and the victimization rate is 39%. Study results demonstrate that adolescents who endorse traditional gender-role beliefs tend to view dating violence as acceptable behavior. Boys' endorsement of traditional gender roles, boys' attitudes justifying boy-on-girl violence, and boys' attitudes against girl-on-boy violence predict boys' actual sexual-violence behavior. Moreover, boys' attitudes justifying boy-on-girl dating violence is the strongest predictor of boys' perpetration of physical and sexual dating violence. This study also shows that boys' hostility is a significant predictor of boys' controlling behavior. Programs for preventing dating violence should include components designed to challenge traditional gender-role beliefs and attitudes justifying dating violence.

  9. Radiocarbon dating of iron artefacts

    Energy Technology Data Exchange (ETDEWEB)

    Cresswell, R. [Australian National Univ., Canberra, ACT (Australia). Dept. of Nuclear Physics

    1997-12-31

    Iron artefacts are generally dated by association or on stylistic grounds. This may not give a true indication of the date of manufacture, or may not be possible if the piece is out of context, ambiguous in style, or a copy. Obtaining a direct date on the artefact would be preferable. During the processes of manufacture, carbon is incorporated into the iron from the fuel source. If the fuel is of a material containing contemporaneous carbon, i.e. has an ambient radiocarbon signature, e.g. charcoal, then we may reliably radiocarbon date the artefact by extracting this carbon. Care must be taken, however, to ensure that re-working has not introduced multiple sources of carbon that would give an erroneous date. Detailed chemical analysis must precede radiocarbon analysis. Sample size is determined by carbon content, and before the advent of accelerator mass spectrometry, several tens of grams of carbon were required for radiocarbon dating (van der Merwe, 1969), prohibiting this method except for high-carbon cast-irons and bulk samples, e.g. caches of nails. AMS permits the analysis of sub-gram pieces of iron (Cresswell, 1991), thereby permitting the analysis of museum pieces with only minimal loss of material, and small fragments of iron recovered from archaeological sites. A few examples are given to illustrate these points. Paper no. 41; Extended abstract. 6 refs.

    Dramatic growth in date (Phoenix dactylifera L.) production, makes it clear to apply proper methods to preserve this nutritious fruit for a long time. Numerous methods have been used to gain this goal in recent years that can be classified into non-thermal (fumigation, ozonation, irradiation, and packaging) and thermal (heat treatment, cold storage, dehydration, jam etc.) processing methods. In this paper these methods were reviewed and novel methods for date preservation were presented.

    2015-07-01

    Full Text Available This article results from a qualitative research, anchored by the methodology of oral history as investigative support. The study aimed to understand the narratives of two young university students about the phenomenon of violence in dating relationships. In this perspective, it is important to unveil the arguments supported in order to mantain a relationship of violence, requiring the understanding of the meanings they attribute to the type of violence suffered. Thus, this study sought to investigate gender violence, that is, the actions or conduct, based on gender differences, which may cause death, physical, sexual or psychological suffering to women, because these events may occur both in the public and private space. Gender violence expresses the historically unequal power relations between men and women.

    2014-10-01

    Empirical evidence has indicated that only a subsample of studies conducted reach full-text publication and this phenomenon has become known as publication bias. A form of publication bias is the selectively delayed full publication of conference abstracts. The objective of this article was to examine the publication status of oral abstracts and poster-presentation abstracts, included in the scientific program of the 82nd and 83rd European Orthodontic Society (EOS) congresses, held in 2006 and 2007, and to identify factors associated with full-length publication. A systematic search of PubMed and Google Scholar databases was performed in April 2013 using author names and keywords from the abstract title to locate abstract and full-article publications. Information regarding mode of presentation, type of affiliation, geographical origin, statistical results, and publication details were collected and analyzed using univariable and multivariable logistic regression. Approximately 51 per cent of the EOS 2006 and 55 per cent of the EOS 2007 abstracts appeared in print more than 5 years post congress. A mean period of 1.32 years elapsed between conference and publication date. Mode of presentation (oral or poster), use of statistical analysis, and research subject area were significant predictors for publication success. Inherent discrepancies of abstract reporting, mainly related to presentation of preliminary results and incomplete description of methods, may be considered in analogous studies. On average 52.2 per cent of the abstracts presented at the two EOS conferences reached full publication. Abstracts presented orally, including statistical analysis, were more likely to get published. © The Author 2013. Published by Oxford University Press on behalf of the European Orthodontic Society.

    1981-01-01

    Obsidian hydration dating of volcanic events had been compared with ages of the same events determined by the 14C and KAr methods at several localities. The localities, ranging in age from 1200 to over 1 million yr, include Newberry Craters, Oregon; Coso Hot Springs, California; Salton Sea, California; Yellowstone National Park, Wyoming; and Mineral Range, Utah. In most cases the agreement is quite good. A number of factors including volcanic glass composition and exposuretemperature history must be known in order to relate hydration thickness to age. The effect of composition can be determined from chemical analysis or the refractive index of the glass. Exposure-temperature history requires a number of considerations enumerated in this paper. ?? 1981.

    2013-09-01

    This study examined the prevalence and reporting of date rape among female college students (aged 18-24) in Cyprus and assessed the students' attitudes and awareness regarding date rape. In addition, the study examined how date rape is perceived among representatives of related private and governmental organizations in Cyprus. This is part of a larger multi-country study. This paper will focus only on the results pertaining to Cyprus. The study was coordinated by the Mediterranean Institute of Gender Studies. This study used quantitative and qualitative methods. In total, 476 female college students responded to an anonymous questionnaire, two focus group discussions were carried out, and five key-informant interviews with relevant institutional representatives were conducted. The results of the study indicated that unwanted sexual experiences and sexual violence, including date rape, do exist among young Cypriot women. Specifically, 1.3% of the research participants reported experiencing an attempted rape by their date, and 1.9 % of the study participants reported being raped on a date. Often this was caused by their boyfriend, friend or sexual partner (54.2%). The results of the qualitative study showed that young female Cypriots agreed that many women give in to psychological pressure because they feel guilty about letting the other person down or because they 'didn't satisfy him' or fear they might lose him. Despite the explorative nature of the study, it is significant as research on date rape in Cyprus is almost non-existent. The authors anticipate that the results of the study will be useful to other researchers and policy-makers involved in this area of research.

  1. Rise and fall of public opposition in specific social movements. [Including nuclear power plants

    This article reports a comparative study of four 'specific' social movements which involve aspects of technological controversy: Fluoridation, the ABM, Nuclear Power Plants, and Legalized Abortion. A theoretical model of the rise and fall of public opposition in these movements over time is suggested. Quantitative indicators are developed and applied to this historical model. Rise and fall of controversy follows a regular sequence: Activities of protest leaders increase during periods of great national concern over issues that are complementary to the movement; during these periods, social and economic resources are relatively available to the movement. As the activity of protest leaders increases, mass media coverage of their activities increases. As mass media coverage increases, opposition to the technology among the wider public increases. As the activity of the leaders wanes, mass media coverage declines, and so does opposition among the wider public. The paper concludes with a discussion of the relevance of this perspective for making predictions about the future course of 'specific' social movements.

    Over a quarter of young women have experienced some form of violence within a dating relationship. The experience of dating violence is associated with problems in psychological functioning, including symptoms of anxiety and depression. However, not all women who experience dating violence exhibit anxious or depressive symptoms. One factor that may influence symptom expression is interpersonal style. In this study, we examined the main and moderating effects of dimensions of interpersonal style (dominance and warmth) on the association between dating violence and symptoms of anxiety and depression. Warmth exhibited a main effect on anxious and depressive symptoms over and above the effects of dating violence and other life stressors. Dominance moderated the association between dating violence and anxious and depressive symptoms. When levels of dating violence were high, women with higher levels of dominance reported fewer symptoms of anxiety and depression than women with lower dominance. These results indicated that whereas high warmth was associated with fewer symptoms of psychopathology generally, high dominance was a buffer against the effect of dating violence on symptoms more specifically. Directions for future research are discussed.

    Information about an individual's place and date of birth can be exploited to predict his or her Social Security number (SSN). Using only publicly available information, we observed a correlation between individuals' SSNs and their birth data and found that for younger cohorts the correlation allows statistical inference of private SSNs. The inferences are made possible by the public availability of the Social Security Administration's Death Master File and the widespread accessibility of per...

    The development is traced of radiocarbon dating from its birth in curiosity regarding the effects of cosmic radiation on Earth. Discussed in historical perspective are: the significance of the initial measurements in determining the course of developments; the advent of the low-level counting technique; attempts to avoid low-level counting by the use of isotopic enrichment; the gradual appearance of the environmental effect due to the combustion of fossil fuel (Suess effect); recognition of the atmosphere ocean barrier for carbon dioxide exchange; detailed understanding of the mixing mechanism from the study of fallout radiocarbon; determination of the new half-life; indexing and the assimilation problem for the massive accumulation of dates; and the proliferation of measurement techniques and the impact of archaeological insight on the validity of radiocarbon dates.

    Optical long baseline interferometry is a technique that has generated almost 850 refereed papers to date. The targets span a large variety of objects from planetary systems to extragalactic studies and all branches of stellar physics. We have created a database hosted by the JMMC and connected to the Optical Long Baseline Interferometry Newsletter (OLBIN) web site using MySQL and a collection of XML or PHP scripts in order to store and classify these publications. Each entry is defined by its ADS bibcode, includes basic ADS informations and metadata. The metadata are specified by tags sorted in categories: interferometric facilities, instrumentation, wavelength of operation, spectral resolution, type of measurement, target type, and paper category, for example. The whole OLBIN publication list has been processed and we present how the database is organized and can be accessed. We use this tool to generate statistical plots of interest for the community in optical long baseline interferometry.

    Mitra, Monika; Mouradian, Vera E; McKenna, Maria

    2013-08-01

    Children with disabilities are at a higher risk for various forms of violence including sexual violence, bullying, and physical violence compared to those without disabilities. However there are no studies documenting the prevalence of dating violence amongst a population-based sample of adolescents with disabilities. The purpose of this study is to assess the prevalence of dating violence victimization against high schools students with and without disabilities and to examine associations of dating violence with health risks by disability status among high school girls. Data from the 2009 Massachusetts Youth Health Survey were analyzed in 2011 using bivariate and multivariate logistic regression. Among high school students who had ever been on a date, girls (25.9 %, 95 % CI 19.9-31.5) and boys (9.1 %, 95 % CI 5.8-12.4) with disabilities were more likely than girls (8.8 %, 95 % CI 6.8-10.8) and boys (4.5 %, 95 % CI 3.1-5.8) without disabilities to report dating violence. Multivariate analyses indicated that high school girls with disabilities who experienced dating violence were more likely to report feeling sad or hopeless for 2 weeks or more in the past year, suicide ideation in the past 12 months, and drug use in the past 30 days compared to those with disabilities who did not report dating violence and those without disabilities who reported and did not report dating violence. High school students with disabilities are at a greater risk for dating violence victimization compared to those without disabilities and high school girls with disabilities who experience dating violence are at increased risk for experiencing poor mental health outcomes and substance abuse.

    2009-01-01

    Dating ancient Chinese porcelain is one of the most important and difficult problems in porcelain archaeological field. Eighteen elements in bodies of ancient celadon porcelains fired in Southern Song to Yuan period (AD 1127-1368) and Ming dynasty (AD 1368-1644), including La, Sm, U, Ce, etc., were determined by neutron activation analysis (NAA). After the outliers of experimental data were excluded and multivariate normal distribution was tested, and Bayesian classification was used for dating of 165 ancient celadon porcelain samples. The results show that 98.2% of total ancient celadon porcelain samples are classified correctly. It means that NAA and Bayesian classification are very useful for dating ancient porcelain. (authors)

  17. Simulation-Based Learning Environments to Teach Complexity: The Missing Link in Teaching Sustainable Public Management

    Directory of Open Access Journals (Sweden)

    Michael Deegan

    2014-05-01

    Full Text Available While public-sector management problems are steeped in positivistic and socially constructed complexity, public management education in the management of complexity lags behind that of business schools, particularly in the application of simulation-based learning. This paper describes a Simulation-Based Learning Environment for public management education that includes a coupled case study and System Dynamics simulation surrounding flood protection, a domain where stewardship decisions regarding public infrastructure and investment have direct and indirect effects on businesses and the public. The Pointe Claire case and CoastalProtectSIM simulation provide a platform for policy experimentation under conditions of exogenous uncertainty (weather and climate change as well as endogenous effects generated by structure. We discuss the model in some detail, and present teaching materials developed to date to support the use of our work in public administration curricula. Our experience with this case demonstrates the potential of this approach to motivate sustainable learning about complexity in public management settings and enhance learners’ competency to deal with complex dynamic problems.

    Dating abuse is a prevalent adolescent health problem with substantial public health consequences. As many as 1 in 10 high school students in the United States reports being "hit, slapped, or physically hurt on purpose" by his or her boyfriend or girlfriend in the past year. The authors used the Rihanna-Chris Brown dating abuse incident of 2009 as a case study to conduct what is, to our knowledge, the first assessment of media framing of dating abuse. The authors reviewed the 20 leading U.S. single-copy sales magazines published from February to April 2009 and identified 48 relevant articles, which were all printed in 7 tabloid magazines. The authors conducted a content analysis of the media frames of the articles using 5 frame categories: (a) abuse is objectionable, (b) victim-blaming, (c) abuse is sexualized/romanticized, (d) myths about abuse perpetration, and (e) abuse is normalized. Abuse is objectionable was the dominant frame of 40% of articles, victim-blaming in 36%. Although the majority of articles reviewed (83%) made at least passing reference to the idea that abuse is wrong, a minority (40%) used a dominant frame that condemned abuse. Instead, the majority of articles communicated mixed messages about dating abuse, and many minimized the seriousness of partner abuse perpetration. Advocacy is needed to improve future tabloid media framing of dating abuse incidents.

  1. Thermoluminescence dating of pottery

    International Nuclear Information System (INIS)

    Higashimura, Takenobu; Ichikawa, Yoneta.

    1978-01-01

    This report is divided into two parts. The first half describes on the history of thermoluminescence dating, and the latter half, the principle and measurement examples. It was in late 1955 that the measurement of radiation dose using thermoluminescence began. The method to thermoluminescence dating was developed when it was found that most natural stones emit the thermoluminescence. About Greek earthen wares, the study of which was presented in 1961 by G. Kennedy of University of California, the dating was able to be made within the standard deviation of 10%. Since then, this dating method progressed rapidly, and a number of laboratories are now forwarding the investigation. In the samples of natural materials, intensity of thermoluminescence I is proportional to natural radiation dose D which has been absorbed by the samples, i.e. I = kD, where k is the susceptibility of thermoluminescence of the samples. Since k is different in each sample, D can be determined by irradiating the sample with β or γ ray of known dose D 0 , measuring its luminescence I 0 , and eliminating k through these two equations, because i 0 = kD 0 . Next, if t is assumed to be the time passed since a pottery was made, D is expressed as Rt, where R is the natural radiation dose per year absorbed by the pottery. Thus t is determined if R is known. The report describes on the method of measuring R. As an example, the results of measurement of the potteries excavated at Iwakura remains, Yorikura, Taishaku-kyo, are listed. Results by 14 C dating are also described for reference. (Wakatsuki, Y.)

    This paper describes the approach taken by the US Department of Energy to ensure that public safety is maintained during transport of core debris from the Unit-2 reactor at the Three Mile Island Nuclear Power Station near Harrisburg, PA, to the Idaho National Engineering Laboratory near Idaho Falls, ID. It provides up-to-date information about public response to the transport action and discusses DOE's position on several institutional issues. The authors advise that planners of future transport operations be prepared for a multitude of comments from all levels of federal, state, and local governments, special interest groups, and private citizens. They also advise planners to keep meticulous records concerning all informational transactions. 3 figs

  4. Ar-Ar dating techniques for terrestrial meteorite impacts

    Science.gov (United States)

    Kelley, S. P.

    2003-04-01

    The ages of the largest (>100 km) known impacts on Earth are now well characterised. However the ages of many intermediate sized craters (20-100 km) are still poorly known, often the only constraints are stratigraphic - the difference between the target rock age and the age of crater filling sediments. The largest impacts result in significant melt bodies which cool to form igneous rocks and can be dated using conventional radiometric techniques. Smaller impacts give rise to thin bands of melted rock or melt clasts intimately mixed with country rock clasts in breccia deposits, and present much more of a challenge to dating. The Ar-Ar dating technique can address a wide variety of complex and heterogeneous samples associated with meteorite impacts and obtain reasonable ages. Ar-Ar results will be presented from a series of terrestrial meteorite impact craters including Boltysh (65.17±0.64 Ma, Strangways (646±42 Ma), and St Martin (220±32 Ma) and a Late Triassic spherule bed, possibly representing distal deposits from Manicouagan (214±1 Ma) crater. Samples from the Boltysh and Strangways craters demonstrate the importance of rapid cooling upon the retention of old ages in glassy impact rocks. A Late Triassic spherule bed in SW England is cemented by both carbonate and K-feldspar cements allowing Ar-Ar dating of fine grained cement to place a mimimum age upon the age of the associated impact. An age of 214.7±2.5 Ma places the deposit with errors of the age of the Manicouagan impact, raising the possibility that it may represent a distal deposit (the deposit lay around 2000 km away from the site of the Manicouagan crater during the Late Triassic). Finally the limits of the technique will be demonstrated using an attempt to date melt rocks from the St Martin Crater in Canada.

  6. Dating the humans by radiocarbon

    International Nuclear Information System (INIS)

    Fedi, M.E.

    2011-01-01

    Radiocarbon has become a very powerful tool used for dating. This paper deals with a specific application of 1 4C i.e. dating of humans. Attention is focused on those aspects that, if neglected, might lead to a misinterpretation of the results or to an unsatisfying accuracy of the measurement. After a brief description of the main principles on which the radiocarbon method is based and of Accelerator Mass Spectrometry, examples taken from the research activity of INFN-LABEC (Laboratorio di Tecniche Nucleari per I Beni Culturali) in Florence are presented. The case of the relic of St. Francis represents an example of dating not directly human remains but other objects that can be associated to them. The case of two burials from the archaeological area of Baratti-Populonia, in Tuscany, gives the possibility to show the importance of estimating the human palaeodiet when dating bone samples.

  7. Family Structure, Maternal Dating, and Sexual Debut: Extending the Conceptualization of Instability.

    Science.gov (United States)

    Zito, Rena Cornell; De Coster, Stacy

    2016-05-01

    Family structure influences the risk of early onset of sexual intercourse. This study proposes that the family structures associated with risk-single-mother, step-parent, and cohabiting-influence early sexual debut due to family instability, including shifts in family structure and maternal dating, which can undermine parental control and transmit messages about the acceptability of nonmarital sex. Previous research has not considered maternal dating as a component of family instability, assuming single mothers who date and those who do not date experience comparable levels of family disruption and transmit similar messages about the acceptability of nonmarital sex. Hypotheses are assessed using logistic regression models predicting the odds of early onset of sexual intercourse among 9959 respondents (53 % female, 47 % male) from the National Longitudinal Study of Adolescent to Adult Health. Respondents were ages 12-17 at the first wave of data collection and 18-26 at the third wave, when respondents reported the age at which they first had sexual intercourse. Results show that maternal dating is a source of family instability with repercussions for early sexual debut. Parental control and permissive attitudes towards teenage sex and pregnancy link at-risk family structures and maternal dating to early sexual initiation among females, though these variables do not fully explain family structure and maternal dating effects. Among males, the influence of maternal dating on early sexual debut is fully explained by the learning of permissive sexual attitudes.

  8. Record date in Serbian company law

    2011-01-01

    Full Text Available The right of the shareholder to participate in and vote at the general meeting is determined based on the shares he holds on a certain date prior to the general meeting (record date. However, the rules regulating the record date deviate from the principle of indivisibility of shares. In extreme cases it is possible to have persons, none of which are shareholders at a given time, to participate in and vote at the general meeting. Hence, it is possible to have persons with no investment interest in the company to decide, for example, on adoption of financial reports, or on disposal of high-value assets. This issue, by its virtue, is not put forward in cases where there was no transfer of shares in the period between the record date and the date of the general meeting.

    2017-01-01

    Sidereal time and Julian date are two values often used in observational astronomy that can be tedious to calculate. Fortunately, the U.S. Naval Observatory (USNO) has redesigned its on-line Sidereal Time and Julian Date (JD) calculators to provide data through an Application Programming Interface (API). This flexible interface returns dates and times in JavaScript Object Notation (JSON) that can be incorporated into third-party websites or applications.Via the API, Sidereal Time can be obtained for any location on Earth for any date occurring in the current, previous, or subsequent year. Up to 9999 iterations of sidereal time data with intervals from 1 second to 1095 days can be generated, as long as the data doesn’t extend past the date limits. The API provides the Gregorian calendar date and time (in UT1), Greenwich Mean Sidereal Time, Greenwich Apparent Sidereal Time, Local Mean Sidereal Time, Local Apparent Sidereal Time, and the Equation of the Equinoxes.Julian Date can be converted to calendar date, either Julian or Gregorian as appropriate, for any date between JD 0 (January 1, 4713 BCE proleptic Julian) and JD 5373484 (December 31, 9999 CE Gregorian); the reverse calendar date to Julian Date conversion is also available. The calendar date and Julian Date are returned for all API requests; the day of the week is also returned for Julian Date to calendar date conversions.On-line documentation for using all USNO API-enabled calculators, including sample calls, is available (http://aa.usno.navy.mil/data/docs/api.php).For those who prefer using traditional data input forms, Sidereal Time can still be accessed at http://aa.usno.navy.mil/data/docs/siderealtime.php, and the Julian Date Converter at http://aa.usno.navy.mil/data/docs/JulianDate.php.

  11. A Cross-National Comparison of Risk Factors for Teen Dating Violence in Mexico and the United States.

    Involvement in dating violence has been linked with negative health outcomes including depressive symptomology, substance use, and later expressions of aggressing and victimizing behaviors. Less is known about the prevalence and mental health correlates of teen dating violence in countries like Mexico where adult partner violence is high. Additional research on teen dating violence is also needed, as it may be an important precursor to adult partner violence and linked to other mental health problems. The current study used self-report ratings to assess the similarities and differences in risk factors associated with dating violence among middle school students in Mexico and the United States. The US sample (N us  = 15,099; M us  = 12.8; 49.5% female) included non-Hispanic Caucasian (24.9%), Hispanic American (20.3%), and African American (24.2%) adolescents. The Mexican sample (N Mexico  = 2211; M Mexico  = 13.67; 51% female) included 93.1% adolescents of Hispanic or Latin descent. Logistic regressions showed that dating violence victimization was reported at similar rates in the cross-national samples, though exposure to risk factors like deviant peers and substance use differed significantly by country. Our analyses indicated that, although the country of residence was not significantly associated with dating violence victimization, the strength of the association between some known risk factors and dating violence victimization varied as a function of nationality, such that there was a significant interaction between country of residence, Mexico or the US, and experiencing internalizing symptoms on experiencing physical dating violence victimization. This study contributes to the growing body of literature on dating violence, both inside and outside the US.

    The remains of an ancient wooden boat were unearthed at the Bibong-ri shell mound site. The site was located at Bibong-ri, Bugog-myeon, Changnyeong-gun, Gyeongsangnam-do in South Korea. A substantial fragment of the vessel was discovered in the lowest layer of the site. We collected 17 samples of charcoal and wood from pebble, sand, and shell layers. Sample preparation extracted the carbon from each sample material and converted it into graphite for AMS radiocarbon dating. Radiocarbon dates of the samples indicate that they belong to the Neolithic period and that the boat dates from ca. 5700 BC. To this point, the oldest known boat in the world has been a wooden boat dating from ca. 5500 BC in China. Other ancient boats from around the world include a logboat dating from ca. 3600 BC in Japan and a fleet of wooden boats dating from ca. 3000 BC in Egypt. The Bibong-ri boat is the first boat from the Neolithic period ever found in South Korea and must represent one of the world's oldest known boats.

  18. Combination of archaeomagnetism and thermoluminescence for precision dating

    Science.gov (United States)

    Becker, H.; Göksu, H. Y.; Regulla, D. F.

    Archaeomagnetic dating was applied to two chalk-burning ovens from an early medieval noble-cemetery. Usually this method allows dating by the investigation of the geomagnetic declination and inclination through the thermoremanent magnetisation of baked clay in situ. However, in this case the method resulted in multiple dates since it was not possible to distinguish the brainching of the geomagnetic secular variation curve. Thermoluminescence dating was applied to the same samples to overcome the problem of multiple dates. This first combined application of archaeomagnetism and thermoluminescence for dating yielded A.D. 670±30 for the two ovens, which dates the first stone-church at the site after a wooden predecessor archeologically dated A.D. 620-630.

  20. Dating of fossil hominid: problems and perspectives

    International Nuclear Information System (INIS)

    Poupeau, G.; Danon, J.; Baksi, A.K.

    1984-01-01

    The hominid dating anterior to the Homo Erectus has been based up to now on the rocks and minerals geochronology of vulcanic origem in stratigraphic relation with the fossils. Two methods are widely used, potassium-argon and uranium fission track dating. The vulcanic material dating; lava, lephra, associated with the hominid leavings show big difficults essentially connected to several types of contamination and modification. Two available examples inside the east-african rift show the probelms linked to these dating. The current progresses in the dating methods can contribute by one hand to a better utilization of the K-Ar and fisson track methods for the vulcanic materials. By other hand, with the introduction of new dating methods (thermoluminescence and electron paramagnetic resonance) will be possible to date directly whether the fossil bone itself or the associated sedimentar material. This open new perspectives in particular for every sites which are not inter-stratified with the vulcanic material. (L.C.) [pt

  1. Neighborhood Concentrated Disadvantage and Dating Violence among Urban Adolescents: The Mediating Role of Neighborhood Social Processes.

    2018-03-14

    The link between relationship violence and aspects of neighborhood concentrated disadvantage (e.g., percent of unemployed adults, percent of families below poverty level), has been established. However, the literature examining neighborhood social processes, including informal social control and social cohesion, in relation to adolescent dating violence has shown mixed results with a limited theoretical foundation and methodology. Using a social disorganization theoretical framework, this study examined the mediating role of these neighborhood social processes in the relation between concentrated disadvantage and adolescent dating violence within an urban context. Participants included 605 adult residents in 30 census tracts and 203 adolescents from neighborhoods on the West and South sides of Chicago. Neighborhood-level concentrated disadvantage was measured via Census data, adult residents reported on neighborhood social processes, and youth reported on dating violence. Informal social control was negatively associated with dating violence, and social cohesion was positively associated with dating violence. A multilevel mediation model showed that concentrated disadvantage was related to higher levels of dating violence via lower levels of informal social control. These results extend social disorganization theory to dating violence within an urban context, while also highlighting the important role of neighborhood processes on relationship violence. Implications for research and intervention programming are discussed. © Society for Community Research and Action 2018.

  2. Correction procedures for C-14 dates

    International Nuclear Information System (INIS)

    McKerrell, H.

    1975-01-01

    There are two quite separate criteria to satisfy before accepting as valid the corrections to C-14 dates which have been indicated for some years now by the bristlecone pine calibration. Firstly the correction figures have to be based upon all the available tree-ring data and derived in a manner that is mathematically sound, and secondly the correction figures have to produce accurate results on C-14 dates from archaeological test samples of known historical date, these covering as wide a period as possible. Neither of these basic prerequisites has yet been fully met. Thus the two-fold purpose of this paper is to bring together, and to compare with an independently based procedure, the various correction curves or tables that have been published up to Spring 1974, as well as to detail the correction results on reliable, historically dated Egyptian, Helladic and Minoan test samples from 3100 B.C. The nomenclature followed is strictly that adopted by the primary dating journal Radiocarbon, all C-14 dates quoted thus relate to the 5568 year half-life and the standard AD/BC system. (author)

  3. Recent advances in thermoluminescence dating

    Aitken, M.J.

    1984-01-01

    Initially the application of thermoluminescent dating was to ancient pottery and other baked clay, the detection of forgeries in art ceramics having a particularly powerful impact. In recent years there has been a growing extension of TL into non-pottery materials. Heated flints from paleolithic fire-places is one application. Another is in the dating of igneous rocks from recent volcanic events; formerly this had been impossible on account of the malign phenomenon of non-thermal ('anomalous') fading exhibited by volcanic minerals but this is now being circumvented by utilising TL in the 600 0 C region of the glow curve. TL dating has also been extended to unburnt calcite, one application being stalagmitic floors in paleolithic caves. Another recent development is the use of TL for dating aeolian sediment and some types of waterborne sediment. These developments give prospect of establishing a TL-based chronology, both for archaeology and quaternary research, extending back well beyond the range of radiocarbon, perhaps reaching a million years ago.

    2004-01-01

    A crystal that is submitted to radiation stores energy and releases this energy under the form of light whenever it is heated. These 2 properties: the ability to store energy and the ability to reset the energy stored are the pillars on which time dating methods like thermoluminescence are based. A typical accuracy of the thermoluminescence method is between 5 to 7% but an accuracy of 3% can be reached with a sufficient number of measurement. This article describes the application of thermoluminescence to the dating of a series of old terra-cotta statues. This time measurement is absolute and does not require any calibration, it represents the time elapsed since the last heating of the artifact. (A.C.)

  10. Chromatographic separation of fructose from date syrup.

    Al Eid, Salah M

    2006-01-01

    The objective of this study is to provide a process for separating fructose from a mixture of sugars containing essentially fructose and glucose, obtained from date palm fruits. The extraction procedure of date syrup from fresh dates gave a yield of 86.5% solids after vacuum drying. A process for separating fructose from an aqueous solution of date syrup involved adding the date syrup solutions (20, 30 and 40% by weight) to a chromatographic column filled with Dowex polystyrene strong cation exchange gel matrix resin Ca2 + and divinylbenzene, a functional group, sulfonic acid, particle size 320 microm, with a flow rate of 0.025 and 0.05 bed volume/min, under 30 and 70 degrees C column temperature. After the date sugar solution batch, a calculated quantity of water was added to the column. Glucose was retained by the resin more weakly than fructose and proceeded faster into the water batch flowing ahead. Three fractions were collected: a glucose-rich fraction, a return fraction, and a fructose-rich fraction. The return fraction is based on when the peaks of fructose and glucose were reached, which could be determined by means of an analyzer (polarimeter) based on the property of glucose and fructose solutions to turn the polarization level of polarized light. A high yield of fructose is obtained at 70 degrees C column temperature with a flow rate of 0.025 bed volume/min and date syrup solution containing 40% sugar concentration. The low recovery by weight obtained using date syrup solutions having a sugar concentration of 20 and 30%, encourages the use of a concentration of 40%. However, with the 40% date syrup supply the average concentrations of glucose and fructose in the return fractions were more than 40%, which can be used for diluting the thick date syrup solution extracted from dates.

  13. Gestational dating by metabolic profile at birth: a California cohort study.

    Accurate gestational dating is a critical component of obstetric and newborn care. In the absence of early ultrasound, many clinicians rely on less accurate measures, such as last menstrual period or symphysis-fundal height during pregnancy, or Dubowitz scoring or the Ballard (or New Ballard) method at birth. These measures often underestimate or overestimate gestational age and can lead to misclassification of babies as born preterm, which has both short- and long-term clinical care and public health implications. We sought to evaluate whether metabolic markers in newborns measured as part of routine screening for treatable inborn errors of metabolism can be used to develop a population-level metabolic gestational dating algorithm that is robust despite intrauterine growth restriction and can be used when fetal ultrasound dating is not available. We focused specifically on the ability of these markers to differentiate preterm births (PTBs) (PTBs and term births. Using a linear discriminate analyses-derived linear function, we were able to sort PTBs and term births accurately with sensitivities and specificities of ≥95% in both the training and testing subsets. Assignment of a specific week of gestation in those identified as PTBs resulted in the correct assignment of week ±2 weeks in 89.8% of all newborns in the training and 91.7% of those in the testing subset. When PTB rates were modeled using the metabolic dating algorithm compared to fetal ultrasound, PTB rates were 7.15% vs 6.11% in the training subset and 7.31% vs 6.25% in the testing subset. When considered in combination with birthweight and hours of age at test, metabolic profile evaluated within 8 days of birth appears to be a useful measure of PTB and, among those born preterm, of specific week of gestation ±2 weeks. Dating by metabolic profile may be useful in instances where there is no fetal ultrasound due to lack of availability or late entry into care. Copyright © 2016 The Authors. Published

    2016-02-01

    Full Text Available The increase in antibiotic-resistant bacteria poses a threat to health care worldwide; this has resulted in a revived interest in plant products as adjunct antimicrobial agents to control pathogenic microorganisms. A major plant group used for traditional medicinal applications is Phoenix Dactylifera L, more commonly known as the date palm. Fruit of the date palm have been used customarily in the treatment of intestinal disturbances, hypertension, oedema and gastrointestinal disease, the nomadic tribes in the Middle East have been known to use traditional date syrup as an antimicrobial agent for wound healing. In some cases these ailments can be attributed to or are strongly associated with a variety of bacterial infections and inflammation. Plant-derived products such as date syrup have demonstrated antibacterial activity and can inhibit bacteria through numerous different mechanisms, which may be attributed to bioactive compounds including plant-derived phenolic molecules. Many such products derive their inherent antimicrobial activity from the presence of polyphenols, which cause oxidative damage. This investigation demonstrated that date syrup, and polyphenols extracted from date syrup, the most abundant bioactive constituent of date syrup are bacteriostatic to both Gram positive and Gram negative Escherichia coli and Staphylococcus aureus. We have further shown that the extracted polyphenols independently suppress the growth of bacteria and have observed that date syrup behaves as a prooxidant by generating hydrogen peroxide that mediates bacterial growth inhibition as a result of oxidative stress. at sub-lethal MIC concentrations date syrup demonstrated antioxidative activity by reducing hydrogen peroxide, and at lethal concentrations date syrup demonstrated prooxidant activity that inhibited the growth of E. coli and S. aureus. The high sugar content naturally present in date syrup did not significantly contribute to this effect. These

  16. Collagen Fingerprinting: A New Screening Technique for Radiocarbon Dating Ancient Bone.

    Directory of Open Access Journals (Sweden)

    Virginia L Harvey

    Full Text Available Collagen is the dominant organic component of bone and is intimately locked within the hydroxyapatite structure of this ubiquitous biomaterial that dominates archaeological and palaeontological assemblages. Radiocarbon analysis of extracted collagen is one of the most common approaches to dating bone from late Pleistocene or Holocene deposits, but dating is relatively expensive compared to other biochemical techniques. Numerous analytical methods have previously been investigated for the purpose of screening out samples that are unlikely to yield reliable dates including histological analysis, UV-stimulated fluorescence and, most commonly, the measurement of percentage nitrogen (%N and ratio of carbon to nitrogen (C:N. Here we propose the use of collagen fingerprinting (also known as Zooarchaeology by Mass Spectrometry, or ZooMS, when applied to species identification as an alternative screening method for radiocarbon dating, due to its ability to provide information on collagen presence and quality, alongside species identification. The method was tested on a series of sub-fossil bone specimens from cave systems on Cayman Brac (Cayman Islands, chosen due to the observable range in diagenetic alteration, and in particular, the extent of mineralisation. Six (14C dates, of 18 initial attempts, were obtained from remains of extinct hutia, Capromys sp. (Rodentia; Capromyidae, recovered from five distinct caves on Cayman Brac, and ranging from 393 ± 25 to 1588 ± 26 radiocarbon years before present (yr BP. All of the bone samples that yielded radiocarbon dates generated excellent collagen fingerprints, and conversely those that gave poor fingerprints also failed dating. Additionally, two successfully fingerprinted bone samples were screened out from a set of 81. Both subsequently generated (14C dates, demonstrating successful utilisation of ZooMS as an alternative screening mechanism to identify bone samples that are suitable for 1(4C analysis.

    Scientific publications have become a mainstay of communication among readers, academicians, researchers and scientists worldwide. Although, its existence dates back to 17 th century in the West, Nepal is still struggling to take few steps towards improving its local science for last 50 years. Since the start of the first medical journal in 1963, the challenges remains as it were decades back regarding role of authors, peer reviewers, editors and even publishers in Nepal. Although, there has been some development in terms of the number of articles being published and appearances of the journals, yet there is a long way to go. This article analyzes the past and present scenario, and future perspective for scientific publications in Nepal.

    Labour induction and augmentation with Prostaglandin and Oxytocin are well established as standard practice worldwide. They are safe when used judiciously, but may be associated with maternal and neonatal morbidities. Other safer alternatives have been studied including dates consumption during late pregnancy with various outcomes. The aim of this randomised controlled trial was to investigate the effect of date fruit consumption during late pregnancy on the onset of labour and need for induction or augmentation of labour. A total of 154 nulliparous women with an uncomplicated singleton pregnancy were randomly allocated to either dates-consumer (77) or control group (77). The women in the dates-consumer group had significantly less need for augmentation of labour and longer intervention to delivery interval. There was no significant difference in the onset of spontaneous labour. Dates consumption reduces the need for labour augmentation but does not expedite the onset of labour. Impact statement • Dates fruit consumption during late pregnancy has been shown to positively affect the outcome of labour and delivery. In this study, date consumption reduced the need for labour augmentation with oxytocin but did not expedite the onset of labour. Therefore, dates consumption in late pregnancy is a safe supplement to be considered as it reduced the need for labour intervention without any adverse effect on the mother and child. This further supports the finding of earlier studies.

    Dating applications (apps) on smartphones have become increasingly popular. The aim of this study was to explore the association between the use of dating apps and risky sexual behaviours. Data were collected in four university campuses in Hong Kong. Subjects completed a structured questionnaire asking about the use of dating apps, sexual behaviours, and sociodemographics. Multiple linear and logistics regressions were used to explore factors associated with sexual risk behaviours. Six hundred sixty-six subjects were included in the data analysis. Factors associated with having unprotected sexual intercourse with more lifetime sexual partners included use of dating apps (β = 0.93, pdating apps (adjust odds ratio: 0.52, pdating apps (adjust odds ratio: 1.93, pdating apps and sexual risk behaviours, suggesting that app users had greater sexual risks. Interventions that can target app users so that they can stay safe when seeking sexual partners through dating apps should be developed.

  1. Damascus steels: history, processing, properties and carbon dating

    International Nuclear Information System (INIS)

    Wadsworth, J.

    2007-01-01

    In the mid-1970s, a class of steels containing high levels of carbon (∼ 1-2 wt% C) was developed for superplastic characteristics - that is, the ability to plastically deform to an extraordinary degree in tension at intermediate temperatures. Because these steels also had excellent room temperature properties, they were developed for their commercial potential. In the late 1970s, we became aware of the striking compositional similarities between these modern steels and the ancient steels of Damascus. This observation led us to revisit the history and metallurgy of Damascus steels and related steels. The legends and origins of Damascus steel date back to the time of Alexander the Great (323 BC) and the medieval Crusades (11th and 12th century AD), and this material has also been the subject of scrutiny by famous scientist in Europe, including Michael Faraday. Modern attempts to reproduce the legendary surface patterns which famously characterized Damascus steels are described. The extend to which the characteristics of Damascus steels are unusual is discussed. Finally, a program on radiocarbon dating was initiated to directly determine the age of about 50 ancient steels, including a Damascus knife, and the results are summarized. (author)

    Fossils provide the principal basis for temporal calibrations, which are critical to the accuracy of divergence dating analyses. Translating fossil data into minimum and maximum bounds for calibrations is the most important-often least appreciated-step of divergence dating. Properly justified calibrations require the synthesis of phylogenetic, paleontological, and geological evidence and can be difficult for nonspecialists to formulate. The dynamic nature of the fossil record (e.g., new discoveries, taxonomic revisions, updates of global or local stratigraphy) requires that calibration data be updated continually lest they become obsolete. Here, we announce the Fossil Calibration Database (http://fossilcalibrations.org), a new open-access resource providing vetted fossil calibrations to the scientific community. Calibrations accessioned into this database are based on individual fossil specimens and follow best practices for phylogenetic justification and geochronological constraint. The associated Fossil Calibration Series, a calibration-themed publication series at Palaeontologia Electronica, will serve as a key pipeline for peer-reviewed calibrations to enter the database. © The Author(s) 2015.

    Dating is the key to organising all archaeological evidence. Furthermore, the development of dating methods, whether traditional or scientific, illustrates the ingenuity and lateral thinking that make archaeological problem-solving such a fascinating exercise. The development of MINT radiocarbon dating procedures is reviewed. Basic principles and counting techniques are discussed. A sample is converted by chemical methods into a suitable form, such as carbon dioxide followed by the acetylene gas, and the benzene end-product is placed inside a proportional counter to measure the radioactivity of 14 C. Not until some years ago did absolute dates by radiocarbon dating become a reality for prehistoric archaeology in Malaysia where thermoluminescence and fission-track dating had begun to provide a locally applicable dating method some decades earlier. Applications of radiocarbon dating procedures in the fields of archaeology are also discussed. (Author)

    Full Text Available The analytical problems of dating gypsum speleothems with the U-series technique are reviewed. Gypsum speleothems are, in general, very low in U content, challenging the limits of detection methods. Various approaches to dissolving gypsum and isolation of actinides from the matrix include ion-pairing dissolution with magnesium salts and using nitric acid. The most precise dating technique is Thermal Ionization Mass Spectrometry (TIMS, combined with Fe(OH3 scavenging and anionic exchange chromatography. Less satisfactory, but much quicker, is direct retention of actinides from HNO3 by means of TRU resin and MC-ICP-MS detection. We have tested these methods on gypsum speleothems from the Sorbas karst in Spain and from the Naica caves in Mexico.

    Full Text Available Abstract Background Against a background of pandemic threat posed by SARS and avian H5N1 influenza, this study used deliberative forums to elucidate informed community perspectives on aspects of pandemic planning. Methods Two deliberative forums were carried out with members of the South Australian community. The forums were supported by a qualitative study with adults and youths, systematic reviews of the literature and the involvement of an extended group of academic experts and policy makers. The forum discussions were recorded with simultaneous transcription and analysed thematically. Results Participants allocated scarce resources of antiviral drugs and pandemic vaccine based on a desire to preserve society function in a time of crisis. Participants were divided on the acceptability of social distancing and quarantine measures. However, should such measures be adopted, they thought that reasonable financial, household and psychological support was essential. In addition, provided such support was present, the participants, in general, were willing to impose strict sanctions on those who violated quarantine and social distancing measures. Conclusions The recommendations from the forums suggest that the implementation of pandemic plans in a severe pandemic will be challenging, but not impossible. Implementation may be more successful if the public is engaged in pandemic planning before a pandemic, effective communication of key points is practiced before and during a pandemic and if judicious use is made of supportive measures to assist those in quarantine or affected by social isolation measures.

    Complete text of publication follows. Situated at the junction of the Tisza and Zagyva rivers, the territory of the presentday Szolnok town has been nearly continuously inhabited since the beginning of the Neolithic age. Gravures and other written documents attested the presence of bridge(s) over the River Tisza during the centuries. The first bridges were mentioned in 1526 as temporary pontoon bridges used for the needs of the Turkish army. The remainings of an old bridge on the River Tisza were discovered last summer in excavations of the river bank at Szolnok. It was supposed that the remainings found were probably part of the bridge built in 1562, the first wooden bridge over the River Tisza mentioned in the letter of bishop of town Eger [1] but could also been parts of a bridge built much later. Although the mineral water and sodium silicate have penetrated the wood logs resulting in though blackish-brown and hardened by petrifaction samples, the original character of the pylons was still evident. Six timbers (7 samples) have been radiocarbon dated. Samples were physically and chemically pre-treated to remove contamination before they were converted to CO 2 . In order to avoid the 'old wood' effect, in which the inner tree rings may be tenths of years older than the outer ring of sapwood deposited just before the tree died the exterior was removed. Physical treatments consisted of cleaning, sorting, grinding and sieving. Chemical treatment included the standard A/A/A method. The pre-treated samples were combusted to CO 2 in a controlled oxygen stream. The purified CO 2 was trapped and measured by gas proportional counting [2]. Correction for fractionation was done by measuring the δ 13 C PDB value. Calibration of 14 C dates to calendar years was performed using the Calib 4.4.2 program [3]. The results showed the wood sample prepared by A/A/A contained contaminants of more recent carbon material which gave it a more recent date and spread the results over four

    The effect of the concentration temperature on the antioxidant activity, carotenoid and phenolic compounds of date syrup was investigated. Date juice was concentrated at 100  and at "60  in vacuum". After concentration, total phenolic, tannin, non-tannin, flavonoid and carotenoid content were determined spectrophotometrically and high-performance liquid chromatography was used for determination of 5-Hydroxymethyl-2-furfuraldehyde content. The antioxidant activity of date syrup was evaluated by various antioxidant methods including total antioxidant, 2,2-diphenyl-1-picrylhydrazyl free radical scavenging test, ferric reducing antioxidant power and β-carotene bleaching. All date syrups showed strong antioxidant activity accompanied by high total phenolic contents. Results showed that concentration at 100  significantly enhanced the antioxidant activities and total phenolic contents of date syrups compared to vacuum concentration at 60 . A good correlation between the antioxidant activity and total phenolic content and flavonoid was observed.

    To review guidance from professional medical associations to physicians on the Sunshine Act, with a focus on industry support for medical publications. Using 'Sunshine Act' as a search term, we searched PubMed (dates February 2013 to November 2014) and the 'grey literature' using Google and Google Scholar. Online information was extracted from websites of pre-identified professional medical associations. Some professional medical associations have published peer-reviewed recommendations, position statements or general advice on their websites and in journals around the Sunshine Act. Associations also provided broad online educational resources for physicians. There was universal agreement between peer-reviewed publications, including guidelines, for the need for full transparency and disclosure of industry support. Surveys by some professional associations showed variance in opinion on the forecasted impact of the Sunshine Act on physician-industry relationships. There was scarce information specifically related to reporting requirements for industry-supported medical publications. There is a shortage of information for physicians from professional associations regarding the Sunshine Act and support for medical publications. Due to the lack of clear guidance regarding support for publications, there are presently varying interpretations of the Sunshine Act. The literature debates the potential impact of the Sunshine Act and expresses some concerns that physician-enabled innovation in drug development may be hindered.

  20. Ambiguity and violence in adolescent dating relationships.

    2012-08-01

    Little is known about dyadic processes that lead to adolescent dating violence. The purpose of this study was to examine the phenomenon of relationship ambiguity in adolescent dating relationships to better understand how ambiguity contributes to violence and aggression between dating partners. Data were drawn from 88 narratives of young adults who had participated in a study on adolescent dating violence. Interpretive phenomenology was used to produce an in-depth description of the phenomenon of relationship ambiguity. Relationship ambiguity results in differing expectations between partners regarding closeness and intimacy, fidelity, and obligation. These differences lead to conflicts that set the stage for violence and aggression in adolescent dating relationships. A series of recommendations for clinicians working with adolescents are presented. © 2012 Wiley Periodicals, Inc.

  1. Dating ancient monuments by nuclear radiation

    2000-01-01

    In the fifties and sixties several disciplines dealing with chronologies but lacking precise methods of measurements (geology, biology, archaeology and art history) became aware of the radioactive decay as a tool of measuring elapsed time. Among the disciplines that benefit most from physical methods archaeology has to be named first. So was archaeological work revolutionised by the introduction of the C-14 dating method. A wider selection of material became datable after the introduction of luminescence techniques using the effect of nuclear radiation on semiconductors. These minerals are widespread among archaeological materials. In ancient monuments, the objective of this paper, semiconductors almost exclusively form the material basis. Over the last four millennia wood, stone, mortar and fired bricks have been used for the construction of buildings. After discussing methods taking wood as a dating material, a broader view will be given on the results achieved by luminescence dating of fired bricks, mortar and stone. For many years brick dating was performed by thermoluminescence, the recipes followed those of ceramic dating. Preferably multiple aliquot additive dose protocols were used on polymineral fine grain fractions (1-10 μm). It was expected that the error in dating monuments would be smaller compared to ceramic dating, because of the constancy of the environmental conditions which a brick experiences during its lifetime. However, the variability of firing temperatures in brick kilns overthrows this advantage. Therefore, the demands of art historians to fall short of an error margin of 5% could generally not be fulfilled. Especially in medieval or renaissance times the temporal resolution of thermoluminescence is inferior to traditional stylistic dating as long as specific stylistic forms are present. New optical luminescence techniques and a new philosophy of dose evaluation, based on single aliquot regeneration protocols, produce less scatter, and in

    The Peace/Williston Fish and Wildlife Compensation Program is a joint initiative by British Columbia Hydro and the provincial environment ministry to enhance and protect fish and wildlife resources and their habitat in the Williston watershed affected by the construction of the WAC Bennett and Peace Canyon dams on the Peace River. The interest from a fund of $11 million, established by BC Hydro in 1988, is used to maintain the compensation programs. Public input to the ongoing fish and wildlife programs is provided by a public consultation program. To date, the Peace/Williston compensation program has undertaken 93 projects to either conserve or enhance fish and wildlife through habitat improvement and protection. A summary is presented of the activities undertaken by the public consultation program in 1992/93 and public attitudes toward the consultation program. Activities undertaken in the fish and wildlife enhancement program are summarized in appendices. Fisheries programs included stocking, stream fertilization, small lake surveys, preparation of a side channel in Carbon Creek for multi-species spawning, and creation of an artificial spring at Windy Point for spawning purposes. Wildlife programs included channel clearance and vegetation supply improvements to enhance muskrat and beaver habitat; radio monitoring of sheep and elk; studying the feasibility of transplanting elk herds; and purchase of critical ungulate winter habitat lands. 13 figs., 4 tabs

  8. Direct fault dating trials at the Aespoe Hard Rock Laboratory

    International Nuclear Information System (INIS)

    Maddock, R.H.; Hailwood, E.A.

    1993-10-01

    Over seventy rock samples were collected from fault and fracture zones in the Aespoe Hard Rock Laboratory tunnel for a study of direct fault dating techniques. Following microstructural and mineralogical analysis, isotopic, palaeomagnetic and electron spin resonance (ESR) methods were employed in an attempt to determine the age of the most recent movements on the sampled faults. The larger fracture zones contain faultrock assemblages and microstructures which are consistent with a prolonged and polyphase movement history, although the cumulative displacements involved formation of fault gouge cemented by authigenic 'illite'. Dating studies were targeted particularly at the gouge but also at older fault rock and vein phases. ESR dating of quartz graines, separated from gouge from fracture zones NE-4 and NE-3, strongly indicates that the ESR signals have not been reset by fault movements for a minimum time period of several hundred thousand to one million years. Palaeomagnetic dating of gouge from fracture zone NE-4 shows that a stable component of magnetisation overlaps both Precambrian and Permo-Triassic parts of the apparent polar wander curve. The younger age of magnetisation is preferred on geological grounds and by comparison with the isotopic dating results. The magnetisation may correspond to a diagenetic event following fault movement. Palaeomagnetic ages determined on countryrock and epidote vein samples are largely consistent with independent age constraints. K-Ar dating of clay fractions (<2 to <0.05μm) separated from gouge from four faults, including fracture zones NE-4 and NE-3, gave model ages in the range 706-301Ma. Accounting for the effects of contamination by potassium-bearing porphyroclasts, it is likely that authigenic 'illite' was formed at least 250 million years ago, after the most recent significant fault movements. 100 refs., 60 figs., 26 tabs

    The Frontlines of Medicine Project is a collaborative effort of emergency medicine (including emergency medical services and clinical toxicology), public health, emergency government, law enforcement, and informatics. This collaboration proposes to develop a nonproprietary, "open systems" approach for reporting emergency department patient data. The common element is a standard approach to sending messages from individual EDs to regional oversight entities that could then analyze the data received. ED encounter data could be used for various public health initiatives, including syndromic surveillance for chemical and biological terrorism. The interlinking of these regional systems could also permit public health surveillance at a national level based on ED patient encounter data. Advancements in the Internet and Web-based technologies could allow the deployment of these standardized tools in a rapid time frame.

    The association between using smartphone dating applications (apps) and substance use in conjunction with sexual activities was only examined in homosexual men. This association was poorly understood in heterosexual samples. To explore the association between using dating apps and alcohol, and use of recreational drug in conjunction with sexual activities in college students. 666 students from four universities in Hong Kong were recruited in this cross-sectional study in the year 2015. Outcome measures included the use of dating apps, sexual history, and drug and alcohol use. Multivariable logistic regressions were employed. The use of dating apps for more than 1 year was found to be associated with recreational drug use in conjunction with sexual activities (adjusted odds ratio: 7.23). Other risk factors of recreational drug use in conjunction with sexual activities included being bisexual/homosexual male, a smoker, and having one's first sexual intercourse at the age of less than 16 years. The use of dating apps was not a risk factor for alcohol consumption in conjunction with sexual activities. Risk factors for alcohol consumption in conjunction with sexual activities included being older, having monthly income more than HKD5,000, and a smoker. Furthermore, risk factors for alcohol consumption in conjunction with the last sexual activity included currently being in a dating relationship, a smoker, and having sex with a casual partner. Using dating apps is an emerging risk factor of drug misuse. Interventions for practising safe sex and preventing drug use should be targeted at dating app users.

    Electronic cash (e-cash) is definitely one of the most popular research topics in the e-commerce field. It is very important that e-cash be able to hold the anonymity and accuracy in order to preserve the privacy and rights of customers. There are two types of e-cash in general, which are online e-cash and offline e-cash. Both systems have their own pros and cons and they can be used to construct various applications. In this paper, we pioneer to propose a provably secure and efficient offline e-cash scheme with date attachability based on the blind signature technique, where expiration date and deposit date can be embedded in an e-cash simultaneously. With the help of expiration date, the bank can manage the huge database much more easily against unlimited growth, and the deposit date cannot be forged so that users are able to calculate the amount of interests they can receive in the future correctly.

    An analytical technique for dating ground water and polar ice up to a million years old has been successfully tested by scientists at Oak Ridge National Laboratory (ORNL). The system, known as a rare gas atom counter, extends the capabilities of resonance ionization mass spectrometry to include counting single atoms of krypton-81. The counter is composed of a pulsed dye laser operated in tandem with a mass spectrometer to separate the various isotopes of krypton. In a collaborative study, ORNL scientists recently used the method for the first time to count krypton-81 in a liter of ground water removed from a sandstone aquifer near Zurich. Fewer than 1000 krypton-81 atoms were isolated from the ground water samples. According to Bernard Lehman, a collaborating geochemist at the University of Bern, this first test proved that counting the small numbers of krypton-81 atoms necessary to make an estimate of the age of water could actually be done. Among the applications of this method, Lehman says, could be improved siting of locations for the disposal of radioactive wastes

  7. Connecting, synchronising, and dating with tephras : principles and applications of tephrochronology in Quaternary research

    Lowe, D.J.

    2017-01-01

    Tephrochronology is a unique method for linking and dating geological, palaeoecological, palaeoclimatic or archaeological sequences or events. The method relies firstly and fundamentally on stratigraphy and the law of superposition, which apply in any study that connects or correlates deposits from one place to another. Secondly, it relies on characterising and hence identifying or 'fingerprinting' tephra layers using either physical properties evident in the field or those obtained from laboratory analysis, including mineralogical examination by optical microscopy or geochemical analysis of glass shards or crystals (e.g. Fe-Ti oxides, ferromagnesian minerals) using the electron microprobe and other tools. Thirdly, the method is enhanced when a numerical age is obtained for a tephra layer by (1) radiometric methods such as radiocarbon, fission-track, U-series, or Ar/Ar dating, (2) incremental dating methods including dendrochronology or varved sediments or layering in ice cores, or (3) age-equivalent methods such as palaeomagnetism or correlation with marine oxygen isotope stages or palynostratigraphy. Once known, that age can be transferred from one site to the next using stratigraphic methods and by matching compositional characteristics, i.e. comparing 'fingerprints' from each layer. Used this way, tephrochronology is an age-equivalent dating method. (author).

    Five tooth samples from the palaeoanthropological site of Jinniushan were dated with both electron-spin-resonance (ESR) and uranium-series techniques. The ESR age of about 230 ka is in good agreement with the U-series dating result, which confirms the hypothesis of possible coexistence of Homo erect us and Homo sapiens in China. Problems in ESR dating are discussed such as: 1) inappropriate of simple exponential extrapolation for accumulated dose determination; 2)experimental measurement of alpha detection efficiency and radon emanation and 3)selection of U-uptake model

    2013-01-01

    Background: Date is one of the foodstuffs that are produced in tropical areas and used worldwide. Conventionally, methyl bromide and phosphine are used for date disinfection. The toxic side effects of these usual disinfectants have led food scientists to consider safer agents such as ozone for disinfection, because food safety is a top priority. The present study was performed to investigate the possibility of replacing common conventional disinfectants with ozone for date disinfection and microbial load reduction. Materials and Methods: In this experimental study, date samples were ozonized for 3 and 5 hours with 5 and 10 g/h concentrations and packed. Ozonized samples were divided into two groups and kept in an incubator which was maintained at 25°C and 40°C for 9 months. During this period, every 3 month, microbial load (bacteria, mold, and yeast) were examined in ozonized and non-ozonized samples. Results: This study showed that ozonization with 5 g/h for 3 hours, 5 g/h for 5 hours, 10 g/h for 3 hours, and 10 g/h for 5 hours leads to about 25%, 25%, 53%, and 46% reduction in date mold and yeast load and about 6%, 9%, 76%, and 74.7% reduction in date bacterial load at baseline phase, respectively. Appropriate concentration and duration of ozonization for microbial load reduction were 10 g/h and 3 hours. Conclusion: Date ozonization is an appropriate method for microbial load reduction and leads to an increase in the shelf life of dates. PMID:24124432

    Black women’s skin color perceptions were identified utilized qualitative methods. The primary goal was to identify the relevance of these perceptions on their understandings about dating preferences and related beliefs about appropriate scripts using a Black feminist thought framework. Twenty- eight self- identified Black women attending a large university in the southeastern United States were interviewed for this study. Lighter- skin was perceived as being more attractive, and associated with four themes about dating: (a) positive personality traits, (b) increased value in dating contexts, and (c) sexual appeal to men. Therapeutic considerations for addressing skin color concerns with Black female clients, including addressing within group differences and validation of skin color values, are addressed.

  16. Gestational dating by metabolic profile at birth: a California cohort study

    Jelliffe-Pawlowski, Laura L.; Norton, Mary E.; Baer, Rebecca J.; Santos, Nicole; Rutherford, George W.

    2016-01-01

    Background Accurate gestational dating is a critical component of obstetric and newborn care. In the absence of early ultrasound, many clinicians rely on less accurate measures, such as last menstrual period or symphysis-fundal height during pregnancy, or Dubowitz scoring or the Ballard (or New Ballard) method at birth. These measures often underestimate or overestimate gestational age and can lead to misclassification of babies as born preterm, which has both short- and long-term clinical care and public health implications. Objective We sought to evaluate whether metabolic markers in newborns measured as part of routine screening for treatable inborn errors of metabolism can be used to develop a population-level metabolic gestational dating algorithm that is robust despite intrauterine growth restriction and can be used when fetal ultrasound dating is not available. We focused specifically on the ability of these markers to differentiate preterm births (PTBs) (PTBs and term births. Using a linear discriminate analyses-derived linear function, we were able to sort PTBs and term births accurately with sensitivities and specificities of ≥95% in both the training and testing subsets. Assignment of a specific week of gestation in those identified as PTBs resulted in the correct assignment of week ±2 weeks in 89.8% of all newborns in the training and 91.7% of those in the testing subset. When PTB rates were modeled using the metabolic dating algorithm compared to fetal ultrasound, PTB rates were 7.15% vs 6.11% in the training subset and 7.31% vs 6.25% in the testing subset. Conclusion When considered in combination with birthweight and hours of age at test, metabolic profile evaluated within 8 days of birth appears to be a useful measure of PTB and, among those born preterm, of specific week of gestation ±2 weeks. Dating by metabolic profile may be useful in instances where there is no fetal ultrasound due to lack of availability or late entry into care. PMID

  17. Inclusions in bone material as a source of error in radiocarbon dating

    International Nuclear Information System (INIS)

    Hassan, A.A.; Ortner, D.J.

    1977-01-01

    Electron probe microanalysis, X-ray diffraction and microscopic examination were conducted on bone material from several archaeological sites in order to identify post-burial inclusions which, if present, may affect radiocarbon dating of bone. Two types of inclusions were identified: (1) precipitates from ground water solutions, and (2) solid intrusion. The first type consists of calcite, pyrite, humates and an unknown material. The second type includes quartz grains, hyphae, rootlets, wood and charcoal. Precipitation of calcite in a macro-molecular level in bone may lead to erroneaous dating of bone apatite if such calcite was not removed completely. A special technique, therefore, must be employed to remove calcite comletely. Hyphae and rootlets also are likely to induce errors in radiocarbon dating of bone collagen. These very fine inclusions require more than hand picking. (author)

    The use of 14 C dating techniques for samples of organic materials up to 50,000 years old is discussed with especial reference to adjustment necessary to take account of both the most recent figure for the 14 C half-life and also the natural fluctuations in the production of 14 C over 50,000 years. Methods of detection and the accuracy of the measurements are considered. It is hoped that future developments including both the possibility of counting 14 C ions directly using an accelerator as a mass spectrometer, and also the use of laser enrichment techniques will not only push back the radiocarbon calendar to 100,000 years but will also allow the use of much smaller samples than before.

    To investigate the awareness of acquired immune deficiency syndrome (AIDS) knowledge and AIDS-related behaviors among youth students in gay dating sites, and to provide evidences for AIDS prevention education through the internet. The students in gay dating sites, selected by a snowball sampling, were interviewed by questionnaires. Chi-square tests were used to analyze the awareness of AIDS knowledge among the students of different characteristics. The Logistic regression was used to analyze the factors associated with ever testing for HIV. In the study, 469 youth students in gay dating sites filled in the questionnaires, and a total of 442 (94.2%) valid samples were collected. The awareness of HIV/AIDS knowledge for the public among the youth students in gay dating sites was 83.9% (371).The awareness of HIV/AIDS knowledge for the youth students was 77.1% (341), and the rate of ever testing for HIV was 52.0% (230). The awareness of HIV/AIDS knowledge for the public in the students were different in different age groups (P=0.001), different marital statuses (Pdating sites was 75.1% (332), and the rate of multiple sexual partnerships among the youth students was 41.3% (137). Compared with homosexual orientation, sexual orientation as heterosexual (OR=0.282, 95%CI: 0.151 to 0.528) and not sure (OR=0.175, 95%CI: 0.035 to 0.885) were risk factors of ever testing for HIV. Multiple sexual partnerships (OR=2.103, 95%CI: 1.278 to 3.462) were promoting factors of ever testing for HIV. The rate of high-risk behaviors among the youth students in gay dating sites was high. The concern should be raised to heterosexual male students who had tendency to homosexual behavior. The AIDS prevention education should be developed in gay dating sites, to improve the self-protection awareness of the youth students.

    2014-03-01

    Full Text Available OBJECTIVE: The aim was to investigate the physical and psychological dating violence among adolescents with respect to the profiles of directionality - only man perpetrates, only woman perpetrates, and bidirectional, ie, both perpetrate violence. METHODS: Sample was performed by two-stage cluster selection in public and private school in the city of Recife (PE, Brazil, presenting data on 355 adolescents of both sexes between 15 and 19 years old. Psychological violence was measured in dimensions threat, verbal/emotional, and relational. Statistical analyzes incorporated the sampling weight and the complex sample design. RESULTS: Violence is bidirectional in most forms studied (83.9% and girls reported higher levels of perpetration of physical violence, and boys reported more perpetration of relational violence. CONCLUSION: It was concluded that adolescent dating violence shows a pattern where partners attack each other, both physically and psychologically. Future research should study the patterns of these acts of violence, keeping the adolescent couple as the unit of analysis and exploring the context in which such violence occurs.

  4. The post-millennium development goals agenda: include 'end to all wars' as a public health goal!

    2014-09-01

    The process of identifying global post-millennium development goals (post-MDGs) has begun in earnest. Consensus is emerging in certain areas (e.g. eliminating poverty) and conflicts and violence are recognized as key factors that retard human development. However, current discussions focus on tackling intra-state conflicts and individual-based violence and hardly mention eliminating wars as a goal. Wars create public health catastrophes. They kill, maim, displace and affect millions. Inter-state wars fuel intra-state conflicts and violence. The peace agenda should not be the monopoly of the UN Security Council, and the current consensus-building process setting the post-MDG agenda is a rallying point for the global community. The human rights approach will not suffice to eliminate wars, because few are fought to protect human rights. The development agenda should therefore commit to eliminating all wars by 2030. Targets to reduce tensions and discourage wars should be included. We should act now. © The Author(s) 2014.

    Juchem, Christoph; de Graaf, Robin A

    2017-11-01

    Multi-coil (MC) magnetic field modeling has emerged as a viable alternative to conventional field generation based on spherical harmonic shapes, and an active MC community is forming. Although all MC applications share the same modeling concept, the specific MC designs can largely differ as a result of disparities in region of interest (eg, human versus rodent), intended MR application (eg, B 0 shimming versus spatial encoding), or other experimental constraints (eg, available bore space or integration with radiofrequency technology). To date, a lack of detailed information on existing MC designs complicates the assessment and precludes a meaningful comparison. Here, we suggest that future publications involving the MC technique not only report the benefits for the application at hand, but also include an explicit description of the MC wire pattern used. This public multi-coil information (PUMCIN) policy represents a voluntary commitment to promoting free public access to the details necessary for reproducing and benefiting from MC research. The PUMCIN policy is expected to initiate a paradigm shift with respect to the way MC innovation is reported. By setting an example, we hope to encourage the evolving MC community to maximize the benefits for science and society by embracing it.

  7. Lessons learned from evaluating Maryland's anti-drunk driving campaign: assessing the evidence for cognitive, behavioral, and public health impact.

    Science.gov (United States)

    Beck, Kenneth H

    2009-07-01

    The evidence concerning Maryland's anti-drunk driving program, Checkpoint Strikeforce, is reviewed. To date, there is no evidence to indicate that this campaign, which involves a number of sobriety checkpoints and media activities to promote these efforts, has had any impact on public perceptions, driver behaviors, or alcohol-related motor vehicle crashes and injuries. This conclusion is drawn after examining statistics for alcohol-related crashes, police citations for impaired driving, and public perceptions of alcohol-impaired driving risk. Comparisons are also made with other states in the mid-Atlantic region, where similar campaign activities have occurred. Reasons for this failure in Maryland include insufficient levels of enforcement (e.g., too few sobriety checkpoints and vehicle contacts occurred to raise public perceptions of risk pertaining to impaired driving) and inadequate publicity surrounding this campaign. Suggestions for overcoming these problems are offered.

    Dating violence victimization is associated with decreased relationship satisfaction and increased mental health symptomatology. Yet, violent dating relationships often remain intact across time, even when the aggression fails to cease. Thus, research is needed to determine the factors that reduce the negative impact of victimization. One factor may be that abusive dating partners are perceived as supportive by their partners, serving to reduce the negative impact of victimization. The current study sought to examine whether perceived support (i.e., perceptions of support) and capitalization support (i.e., perceptions of support for positive events) moderated and reduced the impact of dating violence victimization on decreased relationship satisfaction and increased depressive symptoms. Using a sample of females in dating relationships (N = 253), results provided partial support for our hypotheses. Implications of these findings and directions for future research are discussed. © The Author(s) 2015.

  10. Umbilical cord blood donation: public or private?

    Science.gov (United States)

    Ballen, K K; Verter, F; Kurtzberg, J

    2015-10-01

    Umbilical cord blood (UCB) is a graft source for patients with malignant or genetic diseases who can be cured by allogeneic hematopoietic cell transplantation (HCT), but who do not have an appropriately HLA-matched family or volunteer unrelated adult donor. Starting in the 1990s, unrelated UCB banks were established, accepting donations from term deliveries and storing UCB units for public use. An estimated 730 000 UCB units have been donated and stored to date and ~35 000 UCB transplants have been performed worldwide. Over the past 20 years, private and family banks have grown rapidly, storing ~4 million UCB units for a particular patient or family, usually charging an up-front and yearly storage fee; therefore, these banks are able to be financially sustainable without releasing UCB units. Private banks are not obligated to fulfill the same regulatory requirements of the public banks. The public banks have released ~30 times more UCB units for therapy. Some countries have transitioned to an integrated banking model, a hybrid of public and family banking. Today, pregnant women, their families, obstetrical providers and pediatricians are faced with multiple choices about the disposition of their newborn's cord blood. In this commentary, we review the progress of UCB banking technology; we also analyze the current data on pediatric and adult unrelated UCB, including the recent expansion of interest in transplantation for hemoglobinopathies, and discuss emerging studies on the use of autologous UCB for neurologic diseases and regenerative medicine. We will review worldwide approaches to UCB banking, ethical considerations, criteria for public and family banking, integrated banking ideas and future strategies for UCB banking.

    Full Text Available Transparent conducting oxides (TCOs are electrical conductive materials with comparably low absorption of electromagnetic waves within the visible region of the spectrum. They are usually prepared with thin film technologies and used in opto-electrical apparatus such as solar cells, displays, opto-electrical interfaces and circuitries. Here, based on a modern database-system, aspects of up-to-date material selections and applications for transparent conducting oxides are sketched, and references for detailed information are given. As n-type TCOs are of special importance for thin film solar cell production, indium-tin oxide (ITO and the reasonably priced aluminum-doped zinc oxide (ZnO:Al, are discussed with view on preparation, characterization and special occurrences. For completion, the recently frequently mentioned typical p-type delafossite TCOs are described as well, providing a variety of references, as a detailed discussion is not reasonable within an overview publication.

  14. Radiocarbon dating of ancient Japanese documents

    International Nuclear Information System (INIS)

    Oda, H.

    2001-01-01

    History is a reconstruction of past human activity, evidence of which is remained in the form of documents or relics. For the reconstruction of historic period, the radiocarbon dating of ancient documents provides important information. Although radiocarbon age is converted into calendar age with the calibration curve, the calibrated radiocarbon age is still different from the historical age when the document was written. The difference is known as 'old wood effect' for wooden cultural property. The discrepancy becomes more serious problem for recent sample which requires more accurate age determination. Using Tandetron accelerator mass spectrometer at Nagoya University, we have measured radiocarbon ages of Japanese ancient documents, sutras and printed books written dates of which are clarified from the paleographic standpoint. The purpose is to clarify the relation between calibrated radiocarbon age and historical age of ancient Japanese document by AMS radiocarbon dating. This paper reports 23 radiocarbon ages of ancient Japanese documents, sutras and printed books. The calibrated radiocarbon ages are in good agreement with the corresponding historical ages. It was shown by radiocarbon dating of the ancient documents that Japanese paper has little gap by 'old wood effect'; accordingly, ancient Japanese paper is a suitable sample for radiocarbon dating of recent historic period.

  16. Impacts of human-related practices on Ommatissus lybicus infestations of date palm in Oman.

    Directory of Open Access Journals (Sweden)

    Khalifa M Al-Kindi

    Full Text Available Date palm cultivation is economically important in the Sultanate of Oman, with significant financial investments coming from both the government and private individuals. However, a widespread Dubas bug (DB (Ommatissus lybicus Bergevin infestation has impacted regions including the Middle East, North Africa, Southeast Russia, and Spain, resulting in widespread damages to date palms. In this study, techniques in spatial statistics including ordinary least squares (OLS, geographically weighted regression (GRW, and exploratory regression (ER were applied to (a model the correlation between DB infestations and human-related practices that include irrigation methods, row spacing, palm tree density, and management of undercover and intercropped vegetation, and (b predict the locations of future DB infestations in northern Oman. Firstly, we extracted row spacing and palm tree density information from remote sensed satellite images. Secondly, we collected data on irrigation practices and management by using a simple questionnaire, augmented with spatial data. Thirdly, we conducted our statistical analyses using all possible combinations of values over a given set of candidate variables using the chosen predictive modelling and regression techniques. Lastly, we identified the combination of human-related practices that are most conducive to the survival and spread of DB. Our results show that there was a strong correlation between DB infestations and several human-related practices parameters (R2 = 0.70. Variables including palm tree density, spacing between trees (less than 5 x 5 m, insecticide application, date palm and farm service (pruning, dethroning, remove weeds, and thinning, irrigation systems, offshoots removal, fertilisation and labour (non-educated issues, were all found to significantly influence the degree of DB infestations. This study is expected to help reduce the extent and cost of aerial and ground sprayings, while facilitating the

    The protection of public health and safety is a principal area of concern in any application of nuclear energy. A health and safety analysis must be conducted and reviewed by appropriate agencies and the final results made available to interested agencies and groups, both public and private, prior to the application. This is especially important for the Plowshare Program - the peaceful uses of nuclear explosives - where the public is to be the ultimate beneficiary. Because public health must be a primary concern in the Plowshare Program, it is essential that the potential risk be weighed against the expected benefits to the public. Public health agencies must play an increasingly important role in the planning and operational stages of the peaceful applications of nuclear explosives and in the final stage of consumer use of Plowshare-generated products. There are many long term and long distance ramifications of the Plowshare Program, such a the potential radiological contamination of consumer products that may reach the consumer at long times after the event or at great distances from the site of the event. Criteria for evaluating public exposure to radiation from these products need to be developed based on sound scientific research. Standards for radioactivity in consumer products must be developed in relation to potential exposure of the public. Above all, a clear benefit to the public with a minimum of risk must be shown. The major purpose of this Symposium on the Public Health Aspects of Peaceful Uses of Nuclear-Explosives is to focus attention on the health and safety aspects, present the results of safety analyses accomplished to date and other information necessary to an understanding of the public health aspects, and to identify areas where additional research is required. A general overview of the total symposium content is presented with emphasis on the relationship of the topics to public health. (author)

  7. Dating method by fission tracks: some Brazilian examples

    International Nuclear Information System (INIS)

    Fonseca, Ariadne do Carmo

    1996-01-01

    The Fission Track method (TF) complements the dating of a interval of tectonic events occurred in low temperatures not detected by another radiometric methods. In the South part of Craton of Sao Francisco the dating of apatites of archaean rocks produced ages TF between 900 and 500 Ma, reflecting the progressive acting of the Brazilian margin mobile belts in the archaean craton areas. Apatite of some igneous and metamorphic rocks of the Braziliana age, in the Faixa Ribeira segment, between the Rio de Janeiro and Salvador cities, produced TF ages between 140 and 80 Ma. The basaltic and alkaline volcanism related to the Atlantic Ocean opening dated from this interval. The TF dating in apatites of the continental margin rocks allowed to date the event. In the Cabo Frio region (Southeastern part of Rio de Janeiro State), titanite and apatite of the Transamazonic orthognaisses produced TF dates between 190 and 80 to 40 Ma. The age around 190 Ma date previously the rift formation precursor of the South Atlantic Ocean opening, while the ages between 80 and 40 Ma were related to the alkaline rocks intrusion. The examples mentioned demonstrate the event diversity which may be dated by the Fission Tracks method, mainly in the craton area and margin belts study

  8. Enhanced Indirect Somatic Embryogenesis of Date Palm Using Low Levels of Seawater.

    Science.gov (United States)

    Taha, Rania A

    2017-01-01

    Date palm tolerates salinity, drought, and high temperatures. Arid and semiarid zones, especially the Middle East region, need a huge number of date palms for cultivation. To meet this demand, tissue culture techniques have great potential for mass production of plantlets, especially using the indirect embryogenesis technique; any improvement of these techniques is a worthy objective. Low levels of salinity can enhance growth and development of tolerant plants. A low level of seawater, a natural source of salinity, reduces the time required for micropropagation processes of date palm cv. Malkaby when added to MS medium. Medium containing seawater at 500 ppm total dissolved solid (TDS) (12.2 mL/L) improves callus proliferation, whereas 1500 ppm (36.59 mL/L) enhances plant regeneration including multiplication of secondary embryos, embryo germination, and rooting.

  9. U-series disequilibrium dating of Quaternary carbonates

    International Nuclear Information System (INIS)

    Stirling, C.

    2006-01-01

    One of the key dating methods used in paleoclimate research utilizes the natural radioactive decay of uranium to thorium in archives containing U-bearing minerals, such as the calcium carbonate forming the skeletons of fossil corals and speleothems. More specifically, this chronometer, commonly referred to as the U-series dating method, is based on the decay of 238 U to its longest-lived intermediate daughters, 234 U and 230 Th, and subsequent decay through to stable isotopes of Pb. It is the respective 250,000 and 75,000 year half-lives of these daughter isotopes, which make the U-series system particularly useful for dating Quaternary climate events spanning the last 600,000 years of Earth's history. The U-series thus bridges the gap between the ∼45,000 year upper limit of conventional radiocarbon dating and the ∼200,000 year lower limit of K-Ar and 40 Ar- 39 Ar dating. 2 refs., 5 figs

    2011-01-01

    This paper brings up-to-date a report by S. Best of initial excavations at Naigani in 1981. The results of subsequent fieldwork in 2000 include the excavation and dating of Lapita-age ovens associated with early settlement and extinct palaeofauna. These include the giant megapode (Megavitiornis altirostris), a species of Ducula pigeon, the giant iguana (Lapitiguana impensa), and probably the endemic crocodile (Volia athollandersoni). The Lapita site of VL 21/5 dates from 900 BC and represents an initial colonising settlement within the Fiji Islands. The period of occupation ended around 750 BC. The significance of Naigani is considered in terms of chronology, ceramic history, economy, extinctions, origins and interactions. (author). 33 refs., 10 figs., 2 tabs.

  13. Kimberley rock art dating project

    International Nuclear Information System (INIS)

    Walsh, G.L.; Morwood, M.

    1997-01-01

    The art's additional value, unequalled by traditionally recognised artefacts, is its permanent pictorial documentation presenting a 'window' into the otherwise intangible elements of perceptions, vision and mind of pre-historic cultures. Unfortunately it's potential in establishing Kimberley archaeological 'big picture' still remains largely unrecognised. Some of findings of the Kimberley Rock Art Dating Project, using AMS and optical stimulated luminescence (OSL) dating techniques, are outlined. It is estimated that these findings will encourage involvement by a greater diversity of specialist disciplines to tie findings into levels of this art sequence as a primary reference point. The sequence represents a sound basis for selecting specific defined images for targeting detailed studies by a range of dating technique. This effectively removes the undesirable ad hoc sampling of 'apparently old paintings'; a process which must unavoidably remain the case with researchers working on most global bodies of rock art

  17. Connecting, synchronising, and dating with tephras : principles and applications of tephrochronology in Quaternary research

    International Nuclear Information System (INIS)

    Lowe, D.J.

    2016-01-01

    Tephrochronology is a unique method for linking and dating geological, palaeoecological, palaeoclimatic or archaeological sequences or events. The method relies firstly and fundamentally on stratigraphy and the law of superposition, which apply in any study that connects or correlates deposits from one place to another. Secondly, it relies on characterising and hence identifying or 'fingerprinting' tephra layers using either physical properties evident in the field or those obtained from laboratory analysis, including mineralogical examination by optical microscopy or geochemical analysis of glass shards or crystals (e.g. Fe-Ti oxides, ferromagnesian minerals) using the electron microprobe and other tools. Thirdly, the method is enhanced when a numerical age is obtained for a tephra layer by (1) radiometric methods such as radiocarbon, fission-track, U-series, or Ar/Ar dating, (2) incremental dating methods including dendrochronology or varved sediments or layering in ice cores, or (3) age-equivalent methods such as palaeomagnetism or correlation with marine oxygen isotope stages or palynostratigraphy. Once known, that age can be transferred from one site to the next using stratigraphic methods and by matching compositional characteristics, i.e. comparing 'fingerprints' from each layer. Used this way, tephrochronology is an age-equivalent dating method. (author).

  1. ESR dating of the fault rocks

    International Nuclear Information System (INIS)

    Lee, Hee Kwon

    2005-01-01

    We carried out ESR dating of fault rocks collected near the nuclear reactor. The Upcheon fault zone is exposed close to the Ulzin nuclear reactor. The space-time pattern of fault activity on the Upcheon fault deduced from ESR dating of fault gouge can be summarised as follows : this fault zone was reactivated between fault breccia derived from Cretaceous sandstone and tertiary volcanic sedimentary rocks about 2 Ma, 1.5 Ma and 1 Ma ago. After those movements, the Upcheon fault was reactivated between Cretaceous sandstone and fault breccia zone about 800 ka ago. This fault zone was reactivated again between fault breccia derived form Cretaceous sandstone and Tertiary volcanic sedimentary rocks about 650 ka and after 125 ka ago. These data suggest that the long-term(200-500 k.y.) cyclic fault activity of the Upcheon fault zone continued into the Pleistocene. In the Ulzin area, ESR dates from the NW and EW trend faults range from 800 ka to 600 ka NE and EW trend faults were reactivated about between 200 ka and 300 ka ago. On the other hand, ESR date of the NS trend fault is about 400 ka and 50 ka. Results of this research suggest the fault activity near the Ulzin nuclear reactor fault activity continued into the Pleistocene. One ESR date near the Youngkwang nuclear reactor is 200 ka

  2. Acceptability of dating violence and expectations of relationship harm among adolescent girls exposed to intimate partner violence.

    Science.gov (United States)

    Lee, Michelle Seulki; Begun, Stephanie; DePrince, Anne P; Chu, Ann T

    2016-07-01

    Little is known about the factors that contribute to adolescents' perceptions of the acceptability of dating violence, particularly among girls who have witnessed intimate partner violence (IPV). Drawing on relevant theory, the current study tests a path model linking frequency of witnessing IPV in childhood, sexist beliefs, and automatic relationship-to-harm associations to acceptability of dating violence. Participants were 79 female adolescents with a mean age of 16.08 years (SD = 1.52) involved in the child welfare system. Participants self-reported frequency of witnessing IPV in childhood, ambivalent sexism, and acceptability of dating violence. A lexical-decision task assessed implicit relationship-to-harm priming, which reflects the degree to which people automatically assume that relationships include harm. Consistent with hypotheses, frequency of witnessing IPV was significantly associated with strength of implicit relationship-to-harm associations. Implicit relationship-to-harm associations and hostile sexism were significantly associated with girls' attitudes that dating violence is acceptable. There was a significant indirect effect of witnessing IPV and acceptability of dating violence through relationship-to-harm associations. The current study provides information that is relevant to dating violence intervention among adolescent girls. Interventions that target girls' schema about relationships-making explicit that healthy relationships do not involve harm-and include education about sexism in society are likely to decrease dating violence risk over time.

  3. CEGB experience of public communication

    International Nuclear Information System (INIS)

    Matthews, R.R.; Usher, E.F.

    1977-01-01

    The paper describes the Board's experience of measures adopted to ensure communication with the public during the planning, construction and operational phases of power station projects. Throughout the planning stage there are a series of consultations with statutory bodies. Initial public reactions have been normally against the changes caused by major development rather than anti-nuclear. By giving information to the public and their representatives about possible projects and their effects, the Board seeks to get public understanding of what is proposed and participation in the decision making processes. To provide information and opportunities to raise topics of concern, the officers responsible will attend public meetings and may promote exhibitions and film shows. Another valuable means of communication with the public is through the local press, who are kept informed of the Board's activities from the outset. Where there is controversy a public enquiry may be held before a decision is made on the applications for statutory permissions to build the power stations. This situation is one of confrontation and in the Board's experience is not the best way of disseminating information. During construction the Board's staff on site are responsible for personal contacts with the community and provisions are made for both local people and visitors to take an individual interest in the progress of work. Before a nuclear station becomes operational a Local Liaison Committee is established to provide a forum for the regular interchange of information with the local authorities and elected representatives of the local community. This information includes plans for the protection of the public in the unlikely event of an accident occurring which causes radioactivity to be released beyond the station boundary. Public open days and guided tours of the station are arranged. Local benefits may be provided by making space and facilities available for recreation, educational

    2011-01-01

    Full Text Available Objective: to describe cultural beliefs and medication-taking-behavior about pregnancy in African-American and Latina women. Design: qualitative study using phenomenological methodology; face-to-face, semi structured interviews and focus group. Thematic analysis was done to obtain themes consistent with the research objective. Setting: Maricopa County, Arizona, Department of Public-health Programs, November 2008 through April 2009.Participants: women seeking public-health services in the greater Phoenix, Arizona.Results: fifteen adult women representing two ethnic groups (seven African-Americans and eight Latinas participated. Themes derived from the interview data included: “The Dilemma: To Become or Not to Become Pregnant;” “The Ideal Stress-free World: Support System;” “Changing Worlds: Wanting Dependency;” and “The Health care System: Disconnection from Pregnancy to Postpartum.”Conclusions: based on the cultural themes: 1. pregnancies were not planned; 2. healthy life-style changes were not likely to occur during pregnancy; 3. basic facts about the biology of sexual intercourse and pregnancy were not understood, and there was no usage of any preconceptional or prenatal medications; and 4. professional health care was not desired or considered necessary (except during delivery. These cultural beliefs can contribute to negative birth outcomes, and need to be considered by pharmacists and other health-care providers. The information gained from this study can guide the implementation of educational programs developed by pharmacists that are more sensitive to the cultural beliefs and points of view of these particular women. Such programs would thus be more likely to be favorably received and utilized.

According to numerous studies being performed in many countries, radon and its progenies contribute significantly in total dose to the public. At that, dose due to inhalation of radon and its progenies is higher than that induced by other radiation sources, including sources used in medicine and those occurring in the environment due to the nuclear fuel cycle activities. Prolonged internal exposure to the human‘s body induced by the radon decay products is one of the key factors in the development of the lung cancer pathology. The recent results of global epidemiological studies, aimed at the risk assessment of indoor radon-induced lung cancer, have initiated the need to improve approaches to the regulation of this problem. International organizations (such as WHO, IAEA, ICRP proposed a strategy of the public radiation protection against radon exposure and adapted this strategy to the up-to-date realities. The recent recommendations not only correct the radon activity concentration being limited in dwellings, but also change its status through converting the action level to the reference one. The strategies for limitation of the public exposure due to this component of natural radiation should be revised at the national level and an action plan for their implementation in the long term perspective should be developed. This paper deals with the key provisions of the recent international recommendations including approaches to regulate the public protection against radon exposure.

    Despite efforts to prevent physical teen dating violence, it remains a major public health issue with multiple negative consequences. This study aims to investigate gender differences in the relationships between exposure to interparental violence (mother-to-father violence, father-to-mother violence), acceptance of dating violence (perpetrated by boys, perpetrated by girls), and self-efficacy to disclose teen dating violence. Data were drawn from Waves 1 and 2 of the Quebec Youth Romantic Relationships Project, conducted with a representative sample of Quebec high school students. Analyses were conducted on a subsample of 2,564 teenagers who had been in a dating relationship in the past 6 months (63.8% girls, mean age of 15.3 years). Path analyses were conducted to investigate the links among exposure to interparental violence, acceptance of violence, self-efficacy to disclose teen dating violence (measured at Wave 1), and physical teen dating violence (measured at Wave 2). General exposure to interparental violence was linked, through acceptance of girl-perpetrated violence, to victimization among both genders and to girls' perpetration of physical teen dating violence. No significant difference was identified in the impact of the gender of the perpetrating parent when considering exposure to interparental violence. Self-efficacy to disclose personal experiences of violence was not linked to exposure to interparental violence or to experiences of physical teen dating violence. The findings support the intergenerational transmission of violence. Moreover, the findings underline the importance of targeting acceptance of violence, especially girl-perpetrated violence, in prevention programs and of intervening with children and adolescents who have witnessed interparental violence.

    Since its invention in the late 1940s, radiocarbon (14C) dating has become an important tool for absolute dating. A prerequisite for the acceptance of this method is consistency between, and compatibility of, 14C dates from different laboratories. To meet these requirements, international laboratory

    Past movement on faults can be dated by measurement of the intensity of ESR signals in quartz. These signals are reset by local lattice deformation and local frictional heating on grain contacts at the time of fault movement. The ESR signals then trow back as a result of bombardment by ionizing radiation from surrounding rocks. The age is obtained from the ratio of the equivalent dose, needed to produce the observed signal, to the dose rate. Fine grains are more completely reset during faulting, and a plot of age vs grain size shows a plateau for grains below critical size : these grains are presumed to have been completely zeroed by the last fault activity. We carried out ESR dating of fault rocks collected from the Yangsan fault system. ESR dates from the this fault system range from 870 to 240 ka. Results of this research suggest that long-term cyclic fault activity continued into the pleistocene

    Objectives In September of 2008 the Texas coast was directly hit by Hurricane Ike. Galveston was flooded by 14 feet of storm surge, affecting most of the Island’s housing and infrastructure. The purpose of the present study is to examine whether youth who did not evacuate (11%), and subsequently were exposed to Hurricane Ike, exhibit higher rates of substance use and physical and sexual teen dating violence (both perpetration and victimization), relative to adolescents who did evacuate. Setting Public high school in southeast Texas that was in the direct path of Hurricane Ike. Participants An anonymous survey was administered in March 2009 to 1,048 high-school students who returned to Galveston post-storm (41% Hispanic, 23% African-American, 27% White). Main Outcome Measures Teen dating violence and substance use. Results Mantel-Haenszel odds ratios, adjusting for age and ethnicity, were computed. Compared to boys who evacuated, non-evacuating boys were more likely to perpetrate physical dating violence and sexual assault, and to be a victim of sexual assault. Non-evacuating boys and girls were more likely than those who did evacuate to report recent use of excessive alcohol, marijuana, and cocaine. Conclusions School personnel, medical personnel, and mental health service providers should consider screening for evacuation status in seeking to identify those adolescents who most need services after a natural disaster. Further, in addition to addressing internalized emotions and psychological symptoms associated with experiencing trauma, intervention programs should focus on reducing externalized behavior such as substance use and teen dating violence.

    Full Text Available The analysis of foreign researches of adolescent dating violence is presented in article. Terminological difficulties which overcoming represents a relevant scientific and practical task are discussed. Adolescent dating violence is treated as a specific phenomenon which should be distinguished from bullying, school violence, etc. The data characterizing frequency of violence in the teenage romantic relations are systematized; it is established that up to 2/3 teenagers in foreign countries have experience of adolescent dating violence either as offenders, or as victims, in structure of the discussed phenomenon into the forefront psychological violence acts. Biographic, individual and psychological and social and environmental predictors of adolescent dating violence are considered. Process of transformation of behavior within adolescent dating violence with transition to more mature, partner or marriage, to the relations is tracked. Special attention is paid to sexual differences in predisposition to commission of adolescent dating violence and also his influence on character of the subsequent "adult" relations.

    The proximity of dating partners in peer friendship networks has important implications for the diffusion of health-risk behaviors and adolescent social development. We derive two competing hypotheses for the friendship-romance association. The first predicts that daters are proximally positioned in friendship networks prior to dating and that opposite-gender friends are likely to transition to dating. The second predicts that dating typically crosses group boundaries and opposite-gender friends are unlikely to later date. We test these hypotheses with longitudinal friendship data for 626 9th grade PROSPER heterosexual dating couples. Results primarily support the second hypothesis: romantic partners are unlikely to be friends in the previous year or share the same cohesive subgroup, and opposite-gender friends are unlikely to transition into dating.
